A police officer explains why he put a camera in a high school bathroom

A police officer is trying to explain why he put a camera in a boy's bathroom at Glen Burnie High School last month. 

Officer Allen Marcus says he did it to get to to stop smoking in the restroom. 

He told investigators the camera didn't have a memory card and couldn't record anything. 

He says it was just there to deter students. 

Anne Arundal County police have decided not to charge Marcus. 

He is back on duty.
