I went to high school in the 90s in a very ghetto area of southern California, and we had several armed security guards. Not once (even since I've been there...over 10 years) has there been a shooting there. I've noticed a theme with these mass shootings. They always take place in nice suburban neighborhoods...never ghetto, and most of the shooters came from middle-class families. Proper education about violence and mental aptitude tests I agree with.
