I'm 25...
You sure know a lot about what is best for others at that ripe old age.
I can introduce you to two people who live close to me who've used concealed handguns to stop violent crime in the past year. One is a 90lb barrista who stopped an attacker at her coffee shop. The other is the owner of a sandwich shop who stopped a man who was mugging a woman at knife point outside his store. But... I guess they are just gun-toting yahoo's in your book.
