DETROIT: Gun goes off at police HQ, injures man An unidentified man shot himself in the hand and thigh Friday afternoon as he attempted to pry a trigger lock off a gun in front of Detroit Police headquarters. He was at police headquarters to register his gun. Commander James Tolbert said the man is not a police officer, but officials were trying to determine if he is a reserve officer. Detroit reserve officers receive similar training in handling weapons as police officers. The gun was not a department-issued weapon, Tolbert said. The man is in serious condition at Detroit Receiving Hospital.
