(AP Photo/Cathleen Allison, File) (Newser) – A former Oakland transit cop convicted of shooting and killing an unarmed man on a subway platform last year was freed today after a year in prison, reports CNN. Johannes Mehserle was sentenced to two years for involuntary manslaughter, but he received one day of good conduct credit for each of the 365 days he served behind bars. Mehserle—a Bay Area Rapid Transit officer at the time of the shooting—says he intended to draw his Taser instead of his gun when he shot a 22-year-old on New Year's Day in 2009. But last November, Mehserle was acquitted of second-degree murder and voluntary manslaughter charges and received the two-year sentence, sparking protests in Oakland that turned violent. Although his attorney pushed for probation, Mehserle told the judge he preferred prison if it would calm the city and keep his family safe. "I shot a man," he said. "I killed a man. It should not have happened."
