Knives don't kill people, people kill people. All kidding aside, at some point we need to start looking at correcting people and their actions. We can't keep passing laws that prohibit people's freedom. I carry a knife with me at all times, not to look for someone to stab, but for utility and self defense. Technically anything can be used as a deadly weapon, even your own hands. I don't want to live in a society where you have to wear the obligatory hand cuffs before you get out of your house in case I decide to get crazy and kill someone with my hands. Life is unfair, and unkind.. unfortunately these are the cards we are dealt in life.
