No no no, watch the full video, the cops told him 7 times to drop the gun, she was yelling "don't you do it Keith don't you do it" don't edit this video so it looks like the cops just randomly shot. They were at a standoff with a MINUTE with him telling him to drop the weapon. This is BS reporting at its finest. 

Look at the WHOLE video people. It's very obvious he wasn't holding just a book
