I don't want to talk politics or guns on this subject because guns have been around for hundreds of yrs and politics even longer ......when I was in high school kids would drive to school with rifles and shot guns hanging on gun racks and you never heard about someone getting shot much less dozens being injured or killed ......so instead of arguing over the weapons used or not used in these mass killings I would like opinions on what motivates todays kids to commit acts of evil that was unheard of 30yrs ago ? what has changed ? what is different about the way kids think today ?
