6 yr olds shouldn't die. Especially if they got shot by a cop

If you haven't heard in the US, a 6 year old white boy in a suburb of Columbus Ohio got shot in the stomach and is now dead. His sister came to the door with a gun, then he came out with a BB gun that looked real, and got shot. She's 15 and i'm sure she didn't know better. That's a story in its own right. But you'd think a cop would have the training to not shoot a little kid when the other is an unarmed teen girl. I don't know why they need to shoot to kill either, shoot him in the shoulder or something. He's not going to go for the gun again if he's bleeding out. I don't know. I think cops need better training and more of it.
