I have handled firearms all my life and with that knowledge I know that I do not want to be armed in a tactical situation. Its is more then firearm skills, If you don't train for the use of lethal force then you should not go into the field prepared with it. Kinda like going out on a medical call after watching "House". That being said on a call last week while examining a customer her dog bit me in the top of the head. I managed the event fine but I am thinking of carrying pepper spray, maybe one of those gelled ones.
