...with a firearm. Some kids are very responsible, others like to torture the family pet. This isn't rocket science, and nothing like that should come as a surprise to the parents.

When you see a parent being interviewed after their kid did something evil, and they say, "he's a good kid. He's never done anything like that before." It's pretty clear they are lying sacks of crap. Bad kids do a lot of really bad small stuff long before they graduate to murder. I'm talking overt acts of evil, not extremely subtle things.

If you have a kid with an evil streak, you don't buy them weapons. No firearms, no swords, knives, crossbows, etc. Why is this difficult to understand?
