It seemed that the police got shot in the chest, but he had a bullet wound in his neck. Why did they hand cuff a dead guy. I think that he was shot four time in the scene, there are only three shot wounds. In the memory the guy shot in the leg dropped the gun on his left side, in the beginning it was sitting on his right. Bullet went through neck, vest protected from chest shot. Must have been shot by someone on the side the police were on. The bullet that his the revolver proves that the gun was pointed at policeman. It seemed that a gun was planted, because the policeman decided the pick up the gun, soon to be told to put it back down. Why did the sniper not pick up the bullet shell
