I do too, and not one has killed anything I didn't intend to kill yet! I don't think that this problem is purely the US. It's everywhere. You just see it in mass in other countries. Here it's one person, there it's an entire bunch of people running amok. I do think a lot of it is the lack of care for mental illness. There is little or no help for people who's family members or even themselves need help regarding mental illness. usually the care falls on the parents or others to handle that person. I know of two of my good family friends that deal with a child with mental illness that they get no help for. Unless they DO shoot up a school, no one considers them to be a problem...yet they are still very ill. They set their own homes on fire, threaten family members with injury or death, but until they actually do something, no one will help. It's a sad thing....
