On 12 April 2009 two Folsom Police officers allegedly murdered Joseph Han after Han's family called the police to help deal with Han.
Police found Han barricaded in his bedroom.
Han had a hunting knife to defend himself.
Instead of finding less violent ways to de-escalate the situation, the two officers rushed the room, shot, and killed Han.
The lesson to be learned today is that you should never, NEVER, lock yourself in your room with a knife.
The police will come. And they will end your suffering (or whatever) for you.
