Police in Maryland say a man who called himself "a joker" and threatened to shoot up his workplace was in the process of being fired. Police say the 28-year-old man was taken into custody Friday morning. Investigators said he was wearing a T-shirt that said "Guns don't kill people. I do." He was taken into custody for an emergency mental health evaluation and charges are pending.  (AP Photo/Jacquelyn Martin)
