I got my CCP a few years back but never or rarely carried. I have lived in Newark, parts of NYC, and other rough areas and always thought I was hyper aware of my surroundings because of this.
I got robbed and pistol whipped by some blacks last year for 3 dollars and an old Blackberry. Honestly, if I was carrying it would have not done any good except get the gun stolen. They came out of nowhere and I was fiddling with the radio in my friends driveway which was pitch black.
I do carry now though. I have said this before, but handhelds make great pawn items and are easy to get rid of off the internet.
