2442011818_1fe0bca139 While surveillance cameras are rarely a successful tool in preventing crime, they do come in handy after the fact, when it comes to identifying criminals and cops now too. The New York Times reports how, increasingly, cameras are playing a role in gathering “evidence against police officers accused of misconduct.” Officer Patrick Pogan was eventually fired after video proved he was a liar, but his case was just one of many against law enforcement, like Detective Debra Eager. She was “indicted on three felony perjury charges after her testimony before a grand jury about a 2007 drug arrest “starkly contradicted” video surveillance of the event.” |NYT|
