A college newspaper is suing Purdue University, seeking to force the school to release surveillance video its editors believe shows a staff photographer being roughed up by police after he entered a campus building where a student had been fatally shot and stabbed. The Purdue Exponent and the American Civil Liberties Union of Indiana say the photographer's cameras were temporarily confiscated even though he was two floors away from the murder scene and the suspect had been removed at least 30 minutes earlier. The ALCU filed the lawsuit Tuesday in Tippecanoe Superior Court. The Associated Press left phone messages seeking comment from Purdue spokeswoman Liz Evans. Twenty-three-year-old Cody Cousins is charged with murder in the Jan. 21 death of 21-year-old Andrew Boldt inside a classroom filled with other Purdue students.
