Let's not forget that our schools are always target for foreign and domestic terrorism. Our children are at risk. Students that target schools are troubled kids. They either on drugs, violent, fill with hate and need attention by taking innocent lives. Unfortunately, they're roaming around in society rather than getting treatment in a psychiatric hospital.
The definition of terrorism varies, stupid act's of bravado attacking unsuspecting victims which is a cowardly act for those who cannot face reality. The fear is to face reality. Go figure.
