RX,
Really you are off topic but I would refer you to this site:
http://www.gunfacts.info/
and you can learn more about CCW holders and their accidents rates compared to police. Start on page 17 and move thru it.
Untrained people defend themselves successfully by the millions each year. After this post I will not debate you about training. But I think you need to know more facts. Hope you enjoy the read.
