I don't think there were as many violent people in the past with mental disturbances as well. In the sense of wanting fame or revenge against everyone on a mass scale, although there were alot of serial killers but they didn't seem to be suicidal. Mental illness is the bigger issue then guns, no doubt.
Yep, I was on Ritalin a couple years as a teen because I answered 5 out of 8 questions one way, the 'wrong' way.
