In Libya, justice elusive on uprising's anniversary

BENGHAZI, Libya Col. Faraj el-Dersi, who defected to the rebel side from Muammar Qaddafi's police force, was gunned down late last year on the streets of Benghazi, and he bled to death in the arms of his teenage daughter.

The life of Muammar Qaddafi



As Libya on Sunday marked the second anniversary of the start of the uprising that toppled Qaddafi, the death of el-Dersi and nearly 40 other similar slayings are seen as evidence that some in the country are too impatient for a political system that has yet to deliver justice and national reconciliation.

Suspicion in many of the killings of senior security and military officials has fallen on Islamists who were brutally suppressed under Qaddafi. Now, they have become among the most powerful groups in the new Libya, particularly in the east, with heavily armed militias at their command.

And they are settling old scores themselves, rather than wait for transitional justice — the process of society punishing or forgiving the abuses of the old regime.

Mustafa al-Kufi, a 59-year-old former prisoner and political activist, said the various post-Qaddafi governments and the current parliament are all fearful that if they head down the path of transitional justice, many members of the ruling class would be among those punished for past wrongdoing.

"This is a very pressing issue and a core demand in the street," said al-Kufi, who spent 12 years in prison under Qaddafi.

"We need to know who did what and then ask families of the victims for forgiveness. But since this didn't take place, violence will continue because there is no justice.

Like other Arab countries that ousted authoritarian leaders, Libya is now mired in a chaotic and violent transition to a new society. It is plagued by unruly and heavily armed militias that have slowly come under a unified command but remain filled with hard-liners who were in the front line in the war against Qaddafi.

The transition is further complicated by an autonomy movement in the oil-rich east, a central government too weak to exert its authority across the vast desert nation, and heavily armed Islamic extremists who are pressing to fill a power vacuum.

The civil war swept Qaddafi from power, but the bitterness and rage lingers in a country where the authoritarian government imprisoned, tortured and killed its opponents.

Hana al-Gallal, a prominent Benghazi lawyer, said allowing old regime figures to be part of the new order will only fuel more violence.

"Those whose sons were killed, their dreams shattered by the Qaddafi regime, will seek revenge when they see them back in power," she said. "The result is assassinations."

Some of the anger is directed at those who were in the old government — from low-level police officials to ex-ministers who are now police chiefs and lawmakers. That has prompted a push to prevent those with ties to the former leadership from serving in positions of power.

Libya's parliament, the General National Congress, is debating a draft bill that would bar anyone deemed to have had ties to the former regime from state institutions for 10 years. A version of the draft law published on the GNC's website last week listed 36 reasons for excluding Libyans from political life.

They include those who participated in Qaddafi's coup in 1969; members of the notorious Revolutionary Guards, which were formed to hunt down the dictator's opponents; those who took part in reform efforts in the 2000s led by Qaddafi's son, Seif al-Islam; and those who worked for leading magazines, newspapers, news agencies or served as an ambassador under Qaddafi.

The bill's supporters say such sweeping measures are needed to allow the ministries and state institutions in the fledgling democracy to develop free of the toxic influence and corruption of the Qaddafi era and to stop the cycles of bloodshed like what happened in Benghazi.

Pistorius Case: Agent Cancels All Future Races












Oscar Pistorius won't run in any of the future races that the athlete was contracted to compete in, but the Paraylmpic gold medalist's sponsors are still supportive as he faces a murder charge, his agent said today.


The decision to cancel Pistorius' scheduled appearances was made to "allow Oscar to concentrate on the upcoming legal proceedings and to help and support all those involved as they try to come to terms with this very difficult and distressing situation," Peet Van Zyl of In Site Athlete Management said in a statement.


"I have decided that following these tragic events that we have no option but to cancel all future races that Oscar Pistorius had been contracted to compete in," Van Zyl said.


Pistorius was slated to compete in races in Australia and Brazil, as well as at the Drake Relays in Iowa and the Manchester City Games in the U.K.


Van Zyl also said that Pistorius' sponsors and partners are supportive.


"I can confirm that at this point in time, all parties are supportive and their contractual commitments are maintained. They have said they are happy to let the legal process takes its course before making any change in their position," Van Zyl said in the statement.


However, M-Net movies, a subscription-funded South African television channel has pulled their ad campaign featuring Pistorius, tweeting, "Out of respect & sympathy to the bereaved, M-Net will be pulling its entire Oscar campaign featuring Oscar Pistorius with immediate effect."


The agent's announcement comes as family and friends rallied to Pistorius' defense -- saying they believe the Paralympic gold medalist's story that he shot his model girlfriend Reeva Steenkamp by accident after he mistook her for an intruder.

"When you are a sportsman, you act even more on instinct ... it's instinct -- things happen and that's what you do," Pistorius' father Henke Pistorius, 59, told The Telegraph.


The 26-year-old athlete, known as the "Blade Runner" because of the carbon-fiber blades he runs on, was charged Friday with premeditated murder.

If convicted, Pistorius could face at least 25 years in jail.


"All of us saw at firsthand how close [Steenkamp] had become to Oscar during that time and how happy they were. They had plans together and Oscar was happier in his private life than he had been for a long time," Pistorius' uncle Arnold Pistorius said on Saturday.


According to South African newspaper Beeld, Steenkamp was killed nearly two hours after police were called to Pistorius' home to respond to reports of an argument at the complex.


Police said they have responded to disputes at the sprinter's residence before, but did not say whether Steenkamp was involved.


The athlete's best friend said Pistorius called him after the shooting to say "there has been a terrible accident, I shot Reeva," Justin Divaris told the Sunday People.


While his family insists he is not a murderer, prosecutors disagree.


Police sources told local media that Steenkamp was shot through the bathroom door where she may have been trying to hide to save herself.


Reeva Steenkamp


A memorial service for Steenkamp will be held in Port Elizabeth on Tuesday evening, SABC reported. Her body will be flown back for the service before being cremated, her family said.


"Her future has been cut short ... I dare say she's with the angels," said Mike Steenkamp, Reeva Steenkamp's uncle.


The South African reality show Steenkamp competed in premiered Saturday night on SABC as planned and included a special tribute to the slain law school graduate whose modeling career was starting to take off.

False memories prime immune system for future attacks









































IN A police line-up, a falsely remembered face is a big problem. But for the body's police force – the immune system – false memories could be a crucial weapon.












When a new bacterium or virus invades the body, the immune system mounts an attack by sending in white blood cells called T-cells that are tailored to the molecular structure of that invader. Defeating the infection can take several weeks. However, once victorious, some T-cells stick around, turning into memory cells that remember the invader, reducing the time taken to kill it the next time it turns up.












Conventional thinking has it that memory cells for a particular microbe only form in response to an infection. "The dogma is that you need to be exposed," says Mark Davis of Stanford University in California, but now he and his colleagues have shown that this is not always the case.












The team took 26 samples from the Stanford Blood Center. All 26 people had been screened for diseases and had never been infected with HIV, herpes simplex virus or cytomegalovirus. Despite this, Davis's team found that all the samples contained T-cells tailored to these viruses, and an average of 50 per cent of these cells were memory cells.












The idea that T-cells don't need to be exposed to the pathogen "is paradigm shifting," says Philip Ashton-Rickardt of Imperial College London, who was not involved in the study. "Not only do they have capacity to remember, they seem to have seen a virus when they haven't."












So how are these false memories created? To a T-cell, each virus is "just a collection of peptides", says Davis. And so different microbes could have structures that are similar enough to confuse the T-cells.












To test this idea, the researchers vaccinated two people with an H1N1 strain of influenza and found that this also stimulated the T-cells to react to two bacteria with a similar peptide structure. Exposing the samples from the blood bank to peptide sequences from certain gut and soil bacteria and a species of ocean algae resulted in an immune response to HIV (Immunology, doi.org/kgg).












The finding could explain why vaccinating children against measles seems to improve mortality rates from other diseases. It also raises the possibility of creating a database of cross-reactive microbes to find new vaccination strategies. "We need to start exploring case by case," says Davis.












"You could find innocuous pathogens that are good at vaccinating against nasty ones," says Ashton-Rickardt. The idea of cross-reactivity is as old as immunology, he says. But he is excited about the potential for finding unexpected correlations. "Who could have predicted that HIV was related to an ocean algae?" he says. "No one's going to make that up!"

"Argo", "Lincoln" vie for Oscars crown in open race






LOS ANGELES - Steven Spielberg goes into next weekend's Oscars with the most nominations for his presidential "Lincoln" but the momentum is all with Ben Affleck's thriller "Argo" in the Academy Awards home straight.

And while the Hollywood veteran and the young pretender vie for the Oscars best picture crown, several other frontrunners remain hard on their heels, in one of the least predictable Oscar races in recent memory.

Taiwan-born Lee Ang's 3D spectacular "Life of Pi," Osama bin Laden manhunt movie "Zero Dark Thirty" and romcom "Silver Linings Playbook" could all be in with a chance at the Oscars, the climax of Tinseltown's annual awards season.

Spielberg and Lee are frontrunners for best director, while "Lincoln" star Daniel Day-Lewis is widely seen as a shoo-in for best actor. For best actress the hot money is on Jessica Chastain for her part in "Zero Dark Thirty" or "Hunger Games" star Jennifer Lawrence.

But Affleck's Iran hostage drama, despite only winning seven nominations -- against 12 for "Lincoln," 11 for "Life of Pi" and eight each for "Silver Linings Playbook" and "Les Miserables" -- has a clear edge for best picture.

It has swept up top prizes at a string of key awards shows, including the Golden Globes, the Screen Actors Guild (SAG), Producers Guild of America (PGA), the Directors Guild of America (DGA), and Britain's BAFTA last weekend.

Affleck has gotten used to making acceptance speeches over the last two months -- but he has been tightlipped on his prospects for the all-important 85th Academy Awards, to be held at Hollywood's Dolby Theatre next Sunday.

"I just feel so incredibly honoured to be nominated as a producer for this movie. To be here at the big party," he said at the Oscar Nominees Luncheon, the annual gathering of those in the race, held in Beverly Hills on February 4.

Indeed, his best picture nomination is as a co-producer of the film -- along with George Clooney and Grant Heslov -- rather than as a director, a category in which he was not nominated, in a perceived snub.

Snub or no snub, he will be among presenters at the show, along with a Who's Who of A-listers including Halle Berry, Sandra Bullock, Nicole Kidman, Reese Witherspoon, Robert Downey Jr, Samuel L Jackson, and Meryl Streep.

"Family Guy" creator Seth MacFarlane will be hosting, a move organizers hope will attract younger viewers among the hundreds of millions watching live around the world.

Other nominees presenting include Chastain -- best actress frontrunner for playing a relentless CIA agent on the hunt for Osama, in Oscar-winning director Kathryn Bigelow's controversial "Zero Dark Thirty".

But Lawrence, star of the "Hunger Games" blockbuster franchise, could also win the category for her portrayal of mixed-up Tiffany to Bradley Cooper's bipolar ex-teacher in "Silver Linings Playbook".

Cooper is up for best actor, along with Hugh Jackman for "Les Miserables", Joaquin Phoenix for "The Master" and Denzel Washington for "Flight" -- but Day-Lewis is widely forecast for a record third Oscar for his "Lincoln" turn.

For best director, 66-year-old Spielberg will be hoping for his first Oscar since "Saving Private Ryan" in 1999.

But he is up against Lee -- whose "Brokeback Mountain" won best picture in 2006 -- as well as Michael Haneke for his Cannes-winning "Amour", David O Russell for "Silver Linings Playbook" and Benh Zeitlin for "Beasts of the Southern Wild".

Best supporting actor nominees are Alan Arkin for "Argo", Robert De Niro for "Silver Linings Playbook", Philip Seymour Hoffman for "The Master", Tommy Lee Jones for "Lincoln" and Christoph Waltz for "Django Unchained".

For supporting actress Anne Hathaway is tipped to win for performance in "Les Miserables" -- including her heart-wrenching close-up rendition of "I Dreamed a Dream" -- against Amy Adams for "The Master", Sally Field in "Lincoln", Helen Hunt in "The Sessions" and Jacki Weaver in "Silver Linings Playbook".

The Oscars have a musical theme this year, including a performance by Britain's Adele singing the Oscar-nominated 007 theme tune "Skyfall" as well as by Shirley Bassey and Norah Jones, and Barbra Streisand, in her first Oscars turn since 1977.

STORY HIGHLIGHTS


  • Yes, there ARE some rules to the Internet, though, for now they're mainly an inside joke

  • Some rules based on pop culture, some have become Web memes

  • Other rules ominously quote Anonymous

  • Is there a need for rules on the vast and wild Web? Depends on where you stand




Editor's note: In the gallery above, we've selected a handful of our favorite Internet rules, or truths. (You might recognize a few.) What are some of yours? Tell us in the comments. We'll feature some of the best on CNN.


(CNN) -- Hello!


Welcome to the Internet. It's a big place, so let me show you around.


You're approaching Oversharing Pass, where residents routinely post too much information. The Facebook Gorge and Twitter Triangle are particularly nefarious time-sucks. Restraint is advised.


Up ahead is Hyperbole Junction, which is the Worst. Spot. Ever. We recommend that you maintain an even keel and stay to the center; the extreme left and right can be dangerous.


And over there is the infamous Lair of Sociopaths, the home of trolls and loners who mercilessly mock everyone who enters their territory. Watch your step: They may trip you up and you'll fall into the Chasm of Lulz.


Our world isn't all dangerous, of course. You may visit Squee City, where images of cute cats and laughing babies fill the landscape. You'll also meet countless kind strangers, hilarious raconteurs and hard-working fact-checkers. They make it all worthwhile.


Hmm. Maybe it would be easier if you had a guide -- you know, some rules to help you find your way.


What, you didn't know there are rules of the Internet?


Of course there are rules. How do you think we maintain order around here?


A parody of rules


That's a joke.


But there really are some rules of the Internet -- even if they, too, began as kind of a joke.


According to the site KnowYourMeme.com, the Rules began around 2006 as a guide for the Internet collective Anonymous and emerged on the old Encyclopedia Dramatica, a bawdy meme catalog. Soon a version emerged on 4chan, an online bulletin board where most users post anonymously, says Jamie Cohen, director of web/digital media at Hofstra University's School of Communication.


"Chris Poole (4chan's founder) kind of designed it, kind of like a Netiquette rules," he says, describing the unspoken code of conduct that lubricates Internet discourse. (Poole has attributed the rules to Gaia Online, a role-playing community.)


But the rules of the Internet deliberately mocked many of those conventions. The self-reflexive parody fit perfectly with its community's attitude, points out Anthony Rotolo, a professor at Syracuse University's School of Information Studies.


"These jokes are meant to comment on something happening in the world," he says. "Later they get accepted as truisms or become a meme."


The absurdity has been reflected even in the supposed number of rules. Though the best-known first version claimed there were 50 rules, only 18 were listed. Number 1 was initially "Do not talk about Rules 2-33"; no Rules 2-33 were on the list.


The sarcastic attitude was reinforced by the kicker found on Encyclopedia Dramatica. It was a parody of Wikipedia's stub language: "This article is crap. You can help by completely re-writing it."


'Fight Club' and Monty Python


Very quickly, the lists started multiplying and expanding, liberally borrowing from comedy, Web culture and math-science tropes. On one list, a few were designated by complex numbers and mathematical symbols. Some were observations; others were directives.




Some have traced the Internet rules to Chris Poole, the founder of 4chan.



Two rules were taken from "Fight Club": "You do not talk about 4chan (or "/b/," 4chan's random, free-wheeling bulletin board) and "You DO NOT talk about 4chan." One version of Rule 6 stated "There is no Rule 6," which is from a Monty Python sketch. Rule 42, "Always bring a towel," was drawn from Douglas Adams' "The Hitchhiker's Guide to the Galaxy" series. (If you have to ask, read the books.) "Profit," Rule 49, came from "South Park."


Other rules went the reverse direction and became part of mainstream culture. Rule 34 -- "If it exists, there is porn of it" -- is likely the most famous. But there's also "Pics or it didn't happen" (Rule 30), "For every given male character, there is a female version of that character; conversely for every given female character, there is a male version of that character" (Rule 63) and, of course, the corollary to Rule 34 -- "If no porn of it exists at the moment, it will be made" (Rule 35).


Most retained a sense of humor, riffing off established rules and occasionally ending with a giggly "No exceptions."


But a handful were, and remain, as serious as a judge -- notably the three directly about Anonymous (commonly Rules 3-5):


- We are Anonymous.


- We are legion.


- We do not forgive, we do not forget.


The overall Internet rules may have started as a joke, but such ominous language from Anonymous speaks to some of the paradoxes of the Web:


Rules? Why do we need some stinkin' rules?


After all, rules can be helpful -- or divisive. They can create community -- or subvert it.


Even Anonymous, the activist group itself, cuts both ways, says Rotolo. When it hacked the extremist Westboro Baptist Church, many people cheered. But when it goes after less unpopular targets, some cry vigilantism.


Cohen says that the rules themselves try to have it both ways. They're funny until someone gets hurt.


They "play more of a game type of role. They can be bent or broken or cheated or moved around, as you would in any game that has no physical reaction," he says. "That doesn't take into account ever the result of real people being affected by this -- such as teenagers, children, anybody who's seeing things that they shouldn't."


He adds, "There's a lot of rules in there that work for (the creators) more than anyone else. Until they become victims of their own thing, they don't know how powerful the rules are."


Evolving from the Wild West


Of course, the Internet isn't that old, and we're still in its Wild West era in many ways. As the technology evolves from a handful of hackers on Usenet bulletin boards to billions of users on officially sponsored sites, the customs -- the rules -- of the Web will evolve with it.


But we're not talking about the kinds of changes that your family makes to the rules of Monopoly (no, Free Parking is NOT for the pool of money acquired via Chance and Community Chest). We're talking something more expansive: All the established customs of our carbon-based life forms, making way for the instantaneous and virtual modes of silicon-based electronics.


Who knows what new rules may be written?


"When you're in the midst of social change, it's impossible to determine where it's going," says Peter S. Vogel, a former programmer who's now a Dallas-based attorney. "And I think we are in the greatest social change in the history of humans, because there are no boundaries of geography or time."


We haven't even sorted out what happens when the differences in local culture meet global technology. Bruce Umbaugh, a philosophy professor at Webster University in St. Louis who teaches a course on philosophy and technology, argues that not all parts of the world are as tolerant or open-minded as Western democracies.



There's a lot of rules in there that work for (the creators) more than anyone else.
Jamie Cohen, Hofstra University



"There are a lot of other places in the world that are actively using the technology of the Internet to control the free communication among citizens, and to identify critics of the government and hurt them," he says. "We need to be mindful in what we advocate from our perspective that the tools that are implemented on the Net are tools for the global Net."


In other words, citizens of other countries already face actual, enforceable rules -- unlike the folkways established by Web users in the West. Witness the frictions of the Arab Spring, or the restrictions of societies such as North Korea.


It's the kind of perspective that provides a different context for the issues raised by a libertarian, anything-goes Internet. It's hard enough to stop "Star Wars" comment boards from devolving into flamebaiting, meme-generating files of NSFW Yodas.


So for now, we're still making our way through the Series of Tubes, and nobody knows where the boundaries lie. We joke, we grimace and we marvel at the creativity of the hive mind. The Internet is a big place, and countless cultures have set up residence. Eventually, what is now humor may lose its zing; what are now customs may become laws.


Will the rules ever become The Rules? Maybe some future generation will figure out the true guideposts of Internet life, and the singularity will be upon us.


Nah. It'll never happen.


What did we miss? Share your rules for the internet below in the comments. We'll feature some of the best on CNN.

2 firefighters dead, 2 hurt in Texas lodge fire

BRYAN, Texas Two Texas fire lieutenants have died of burns after battling a lodge hall fire, a city official said Saturday.

Greg Pickard and Eric Wallace, both with the department in the Central Texas city of Bryan, were in a group of firefighters responding to the blaze about midnight Friday at a Knights of Columbus hall, city spokeswoman Mary Lynne Stratta said.

The team entered the burning building but didn't emerge when ordered to evacuate, Stratta said.

Wallace, 36, died at the scene and Pickard, 54, on Saturday at a hospital in Galveston, she said.

"He called for help, said he was low on air," Stratta said of Wallace, a 13-year Bryan Fire Department veteran.

With Wallace still inside, Pickard and two other firefighters — Ricky Mantey Jr. and Mitchel Moran — were sent in to rescue him when the roof collapsed in flames, Fire Chief Randy McGregor said.

Rapid response units found the men inside the building. Mantey, 30, and Moran, 21, also were injured. They were taken to the Galveston hospital with burns. On Saturday, Stratta said they were both in serious but stable condition.

The Texas State Fire Marshal's office is investigating the cause of the fire in Bryan, about 90 miles northwest of Houston. A news release from the city said nothing was being held at the hall at the time.

"These four courageous individuals represent the best of the profession and are true heroes in every sense of the word," McGregor said.

Services for Wallace are scheduled for Thursday in Bryan, while those for Pickard, a 32-year veteran of the department, are pending.

Meteor Blast 'Something We Only Saw in Movies'












A day after a massive meteor exploded over this city in central Russia, a monumental cleanup effort is under way.


Authorities have deployed around 24,000 troops and emergencies responders to help in the effort.


Officials say more than a million square feet of windows -- the size of about 20 football fields -- were shattered by the shockwave from the meteor's blast. Around 4,000 buildings in the area were damaged.


The injury toll climbed steadily on Friday. Authorities said today it now stands at more than 1,200. Most of those injuries were from broken glass, and only a few hundred required hospitalization.


According to NASA, this was the biggest meteor to hit Earth in more than a century. Preliminary figures suggest it was 50 feet wide and weighed more than the Eiffel Tower.










SEE PHOTOS: Meteorite Crashes in Russia


NASA scientists have also estimated the force of the blast that occurred when the meteor fractured upon entering Earth's atmosphere was approximately 470 kilotons -- the equivalent of about 30 Hiroshima bombs.


Residents said today they still can't believe it happened here.


"It was something we only saw in the movies," one university student said. "We never thought we would see it ourselves."


Throughout the city, the streets are littered with broken glass. Local officials have announced an ambitious pledge to replace all the broken windows within a week. In the early morning hours, however, workers could still be heard drilling new windows into place.


Authorities have sent divers into a frozen lake outside the city, where a large chunk of the meteor is believed to have landed, creating a large hole in the ice. By the end of the day they had not found anything.


They are not the only ones looking for it.


Meteor hunters from around the world are salivating at what some are calling the opportunity of a lifetime. A small piece of the meteor could fetch thousands of dollars and larger chunks could bring in even hundreds of thousands.

False memories prime immune system for future attacks

Alleged cop killer died from single shot to head






LOS ANGELES: Alleged US cop killer Christopher Dorner died from a single gunshot wound to the head that appeared to be self-inflicted, a coroner said.

The doctor who examined the body concluded that "the cause of death was a single gunshot wound to the head," said San Bernardino County coroner Kevin Lacy, giving details from the results of a six-hour autopsy.

"We are not yet able to speak about the manner of death and tell you whether or not it was the result of a self-inflicted wound or another round," he told a press conference.

But he said, "while we are still assembling the reports and putting it together, the implication seems to be that the wound that took Christopher Dorner's life was self-inflicted."

The ex-Los Angeles Police Department (LAPD) cop went on the run last week after allegedly killing a couple and a policeman, and wounding three people. Another officer was killed and one wounded before the cabin in which Dorner was holed up burned in a fire.

Dorner had posted online a chilling manifesto in which he threatened to kill policemen and their families, and blamed the LAPD for treating him unfairly in his sacking in 2008.

The manhunt came to a climax Tuesday in a cabin near a snow-covered ski resort, after Dorner was spotted in a stolen vehicle and then fled on foot after crashing one vehicle and carjacking another.

San Bernardino County Sheriff John McMahon said that there was a prolonged firefight with the 33-year-old, who barricaded himself in the cabin after a six-day manhunt.

When they had exhausted other means, SWAT officers used a tractor-type device to open up the windows and walls of the cabin, and inserted a pyrotechnic chemical, to try to force Dorner to surrender.

A blaze erupted, starting at one corner of the cabin. As the flames took hold, after a period of no firing, "We heard a distinct single gunshot coming from inside the house," said McMahon.

The sound of it "indicated to me (that) a different kind of weapon had been fired," he added.
