I think another aspect to this is the fact that kids are so preoccupied now. They always have something in front of them, a phone, tablet, computer, video games. You have to actually interact with other people to be violent. This generation is completely distracted with "entertainment" and commercials. I think this is very bad for our country. We are now sedate and complacent. We are much easier to control now (see the last presidential election). A populace needs some fight in them. The human race will never be at peace, we're not made that way. We can stay slightly violent and independent, or become complacent and controlled.
