If someone did a study to find out of all the shootings in the US, how many of them have some serious mental issues. We are not dealing with the issues, we are throwing drugs at them hoping that whatever ails them will be fixed with drugs. I'm sorry to say, but giving people medicine to deal with serious mental issues is not going to solve the problem. We can pass all kinds of gun control, but until we really deal with the mental health of all people, we will still have shootings.
I work in a school and it is scary to think that someone can come to my school and shoot some kids or teachers. But I also see some of the parents with some serious issues and they scare me sometimes. But, they don't think they have any issues, its all the problem of the school. Or, we aren't dealing with some issue the way they want.
I don't have any answers on how to deal with the mental issues of the people who are angry enough to kill, but I know that we need to find some.
