Where do you live? At my previous residence there were four murders within 2 blocks of my home in the three month span before I moved the fuck away from that hood. Three of the murders were between people who knew their killer but one was a random victim shot by a car thief. With incidents this common, good people want to have the ability to protect themselves and loved ones. Unfortunately, that's life in certain parts of the USA.
When I had my old permit and carried a gun, I always found myself much more calm even if someone tried to mess with me or verbally threatened me. I would quickly turn the other cheek. That doesn't mean I was a pussy, I was simply doing everything I could to AVOID having to draw my weapon. Someone could be a total prick to me and I would ignore it. When you know that you have the power to easily kill someone, it's much easier to ignore someone that's being an asshole. You do not ever want to take your weapon out of the holster unless it is ABSOLUTELY necessary.
Well put rob
