You and many others on this site could stand to learn more from instructors such as Rich_S.
Due to the fact that I hold CCL's in several states, I have had the opportunity to take classes from several instructors. Scenarios of weapon use are always a large part of these classes. The response from these instructors has been the same.
No, we as licensees are not " sheep dogs". We are not enforcers of the law. We ONLY use deadly force to defend ourselves or family members. Anything else will cost you time, money and stress in defending your actions in court.
CharlesMorrison is correct when he believes many on this site are "looking for someone to shoot". If you are one of these types then get your weapon and go to any big cities, bad area, late at night. Lots of "bad guys" who will eventually give you reason to shoot.
Me, I will avoid all situations possible, that could lead to the use of my weapon and no, I will not defend you. I will make myself a good witness and notify law enforcement.
Provided you survive your Rich_S Ostrich approach to self defense.
