Not at all car related, but it's relevant to a lot of your interests. It's a presentation by Dr. Frank Conner, the head of the Psychology Dept. at Grand Rapids Community College, on the psychological and cultural issues behind gun violence in America. It's not out to disprove one side or another, it's just a look at gun violence and how to stop it through the eyes of psychology. I know you all can sit through an hour long high school lecture, and this is only 45 minutes longer and it's about stuff that really matters, so no excuses!
EDIT: Changed phrasing because I have nothing better to do.
