You have no common sense in my honest opinion. I've served in the Military Police for 8 years and in corrections on the civilian state level. I know for a fact criminals like to target "easy prey" which most consider schools and family entertainment establishments. The fact is laws will never protect us from criminals. Also mace is a horrible example, mace doesn't affect 90% of criminals, it's just pepper spray, and a lot of cases are out there where people trying to use it spray themselves by accident, so try OC, which is expensive and the same problem of lots of people aren't extremely affected by it, and you don't have to see to attack someone you already have ahold of. So what now?
