for example, when i was a late teen i tried to commit suicide at home, and it could have been prevented if my mom wasnt so blind to what was going on with me.
I'm sorry for your situation, but it's rarely that black and white. Many children don't display symptoms which suggest they might try to commit suicide. In fact, most children in that position deliberately bottle their feelings up which is what results in them trying to kill themselves. Regardless of how good at parenting you are, sometimes there are so few signs that there is little you can do to prevent it from happening.
There's a movie that's come out recently called 2:37 - it was made over here in Adelaide by a few high-school kids. It was based in a school with a wide diversity of personalities, and all we knew at the start was that a tragedy would happen at 2:37 (someone would kill themselves). Throughout the whole movie everyone guessed who was going to wind up committing suicide. When the clock hits 2:37 though, I was surprised to find out that it was the one child who didn't have 'problems' which ended up committing suicide. Often people are so self absorbed with their own lives and their own problems that they don't notice these subtleties, that's even when they are apparent!
Parents might be able to stop some of these school shooting by sitting down and discussing the childs problems. Far too often though, the parent thinks that the child is just going through one of those phases that they'll soon grow out of. Even still, would you blame any parent for NOT thinking that their child was going to shoot a bunch of people at school?
