not sure if the officers are trained to shoot to kill or shoot to disable.  maybe, they should be trained to shoot to disable (arm or leg), especially those with other weapons than a gun.  the last 2 incidents of cop killing on the mainland involved victims who had guns and carried them legally.  I don't believe that guns (legal or illegal) should be used to defend against cops.  so in those states where carrying a gun is legal, then the cops should first  ask the victim if he has  gun and to put his hand on his head and then the cop can handcuft the victim and remove the gun.  then the cop can continue his investigation.  in this case the nra are indirectly responsible for these unnecessary killings.
