soon the arraignment for the parents of the michigan school shooter. at arraignment will begin. and when it does, we will carry it live. question, do police always have to shoot to kill? i've got a warning for you you're about to see a video that contains some disturbing images. all right. roll it. this week in tucson the police department moved to fire an officer in a day he fatally shot a man in a wheelchair. the man was suspected of stealing a toolbox from a walmart. he flashed a knife when challenged. and the officer carrying a taser opted to use his gunfiring nine times. the officer's lawyer said the taser wasn't an option and told richards' actions were to blame. officers are trained when they perceive a deadly 38, they're to fire multiple times. anytime a firearm is discharged it's considered a deadly force.
