I'm in the same boat as Coalcracker, if I go down I'm down for the duration.
But to answer your question, no I do not practice. Though I have a CCP I choose to not carry. However, I'm getting more and more tempted to because of my health, not because I'm worried about finding myself in bad situations.
I was shot at about a year ago while I was working. I found that gangstas are about the worst shots on the planet. Six shots, the closest any one of those shots got to me was about 10 feet and hit a women in the arm (went through the arm and stopped in her breast). Two rounds hit the vehicle I was in, and three hit two vehicles behind the shooter. Those three caused the cops some confusion since there was only one shooter according to the witnesses. I never saw the shooter.
You might ask how I know the shooter was shooting at me. Good question. I drive a party bus, I had an all black folks party on the bus and was at an all black bar in the least wealthiest part of the town where this happened. I was the only caucasian in sight. One lady (?), not part of my bus party was yelling at me because of something she accused me of doing that I didn't do. Everyone said the shooter was a friend of hers and was trying get me.
Having a firearm in that scenario would have made matters worse I think. If I had seen the shooter and drawn my weapon how many more weapons would have come out? It would likely have been me versus the world after that.
(I guess videos have to be supported by YouTube or whatever, so I found a picture of the bullet hole in the window of my party bus instead. >>>
