An FBI investigation prompted by video footage of a man being punched repeatedly in the face by police has demonstrated anew the power of the Internet sensation of the year, YouTube.com. In addition to being a monumental time-waster around the office, YouTube could also become a tool for keeping police honest, some say. This week, a clip on the post-it-yourself video Web site triggered a police-brutality investigation by the FBI. The footage shows the Aug. 11 arrest of alleged gang member William Cardenas, 24. Two Los Angeles officers can be seen holding him down on a Hollywood street; one punches him several times in the face before they are able to handcuff him. The Los Angeles Police Department is also investigating the officers’ conduct.

In fact, on Friday, the Los Angeles Times reported that a Superior Court commissioner viewed the video nearly two months ago, heard the officers’ testimony, and concluded that their conduct was “more than reasonable” because Cardenas was resisting. Cop Watch LA, a police watchdog group, posted the video on YouTube, said organizer Joaquin Cienfuegos. Cienfuegos said the video was shot by a neighbor of Cardenas with a cell-phone camera. The neighbor gave it to Cardenas’ family, who then gave it to Cop Watch, according to Cienfuegos. In recent months, videos posted on YouTube have rocked political campaigns, brought fame – or infamy – to previously unknown talents and cast unwanted attention on the gaffes of the famous. YouTube and similar video sites are also increasingly becoming repositories for videos that purport to detail wrongdoing by police. Such amateur clips help cast a spotlight on police wrongdoing that could otherwise go unreported, said Ramona Ripston, executive director of the American Civil Liberties Union of Southern California. “Unless we throw light onto activities of government, all activities, you never find out what happened,” Ripston said. “This video is an example.” Police said Cardenas had been wanted on charges of receiving stolen property. In an arrest report obtained by The Associated Press, the officers said they tried to arrest Cardenas after spotting him on the sidewalk, but Cardenas ran. The officers caught up to him, tripped him and swarmed over him to apply handcuffs, the report said. In their report, they admitted hitting him repeatedly in the face, saying that he was resisting and that they feared he might grab one of their guns. Cardenas suffered cuts and bruises on his arms, leg and face, and received stitches on an eyelid. His attorney, B. Kwaku Duren, accused the officers of using excessive force. As of Friday, the clip had received more than 155,000 views on YouTube. It was posted on Oct.18. A search on YouTube for the terms “police brutality” found more than 500 videos, including ones that claim to show police violence in the United States and as far away as Egypt and Hungary. A search of Google’s video site also yielded hundreds of videos. In response to the surge in amateur videos, some law-enforcement agencies have installed cameras in squad cars to protect officers against false allegations. Police defense attorney John Barnett said the public shouldn’t draw conclusions when watching the clip of Cardenas’ arrest. Barnett represented one of the officers in the 1991 Rodney King beating and an Inglewood police officer, Jeremy Morse, who was videotaped roughing up a 16-year-old boy. Two juries deadlocked in Morse’s case, and four officers were acquitted in the King trial, touching off riots in Los Angeles. “It’s very difficult to find jurors who haven’t already come to a conclusion,” Barnett said. “The public has the perception of what the facts are, but you have to figure out a way to get them back to square one.” 160Want local news?Sign up for the Localist and stay informed Something went wrong.
