My friends had gotten me into shooting by taking me to the range. It was at that point I started doing my own research into the history of firearm ownership in this country and around the world and crime statistics. One of my friends got one and I followed suite soon after.
I didn't wait for a 'bad' thing to happen to me or my friends/family to get one.
I like CCW but dislike that I have to register with the .gov to get the permit. It really is an indirect form of firearm registration as you have a person, place of residence and at least evidence of ownership.
