Does paranoia count as mental illness?
I saw my cousin yesterday for Xmas. Apparently, she's going off the deep end with this fiscal cliff, bad economy, tightening of the middle class, etc. and is convinced her home will be targeted when the 'class warfare' breaks out, as they have money and the husband is away all week.
She's talking a loaded weapon with a 30 shot clip in just about every room. Not locked away, not keeping the bullets separate from the guns, and debating not keeping the safety on. Her though is optimize response time if soemeone breaks in.
She also has 3 young kids who will be bound to find them when they are snooping around to see what Santa or the Easter bunny will bring. There's just so much that can go wrong. I can totally imagine junior finding it, showing it off to his friends after school one day, and them fooling around with it just right and someone gets shot.
This doesn't address mass murdering crazies, but it's on topic. A lot of gun related injuries/death could be avoided by a little responsibility and safety.
When I was growing up, my grandfather kept a shotgun in the corner of the living room. None of us kids ever played with it. None of us were ever even tempted to play with it. When I was growing up, my parents kept their guns in their room. They weren't locked up. But neither me or my brother ever played with them. Why, because we were taught from day one that they were not toys, that if we ever touched them without permission it would resault in an ass beating, and that if we did want to "look at them" we had to ask and an adult would show them to us.
Hell, even when we were given toy guns, we were given the same "rules" as real guns. One, never point it at anything/another person in less you intend to kill/hurt it/them. Two, always treat a gun as if it is loaded. Three, never put your finger on the trigger untill you intend to fire. And four, always know what is behind where you are going to shoot.
