Every encounter that I've ever dealt with the person told me they ran and called for us. Never did anyone ever tell me they, "tried to put up a fight"
I could have guess you are a LEO. Most LEO's assume everyone else is not proficient with their weapons. And to be honest with ya, If an LEO is there or nearby I would much rather have any confrontation handled by you guys. Thats what your there for. But that is not always an option. I was always told.. whether in the halls at school, out with my buddies as a teenager, or now as an adult who chooses to carry, always remove yourself from the situation/threat if at all possible. But like I said before that may not be an option in certain situations.
