If you Conceal Carry a Gun what is Your Personal ROE?

I use the same ROE as I did when I was working in Law enforcement and has been held up by SCOTUS.

If my life or another's is in danger of death or great bodily harm. Otherwise, I will be a good witness.

COL Mikel J. Burroughs - Mikel; I don't carry 99.99% of the time.

When I do carry then I am prepared to use my weapon to stop/prevent grievous bodily harm and/or the illegal use of weapons to commit crimes.

Unless I am personally threatened, a disabling shot is best and a gut shot tends to be both disabling and more achievable than "shooting the gun out of their hand" - it also allows for the law to run its course.

If I am personally attacked, then all bets are off since only an "insane" person would attack someone who has a drawn firearm and appears to be ready to use it.

COL Mikel J. Burroughs
#1 “You were not at fault or did not create the situation that gave rise to the taking of another’s life.”
#2 “You believe you were in danger of imminent death or great bodily harm.”
#3 “You must not have violated any opportunity to retreat or avoid the danger.”
#4 “You have exhausted all other means to avoid the use of deadly force.”
#5 “The use of deadly force presents no substantial risk of injury to innocent persons.”

My personal response is I can neither confirm nor deny.

Well that is an interesting question COL Mikel J. Burroughs. The ROE would depend upon the environment - grocery store versus crack house, day care versus biker bar :-)
The ROE depend on which state you are and whether or not there are reciprocal enforcement agreements with your home state.

I carry pretty much everywhere I go these days. I attempt to avoid situations where I would need to use it anyway but if I find myself in a situation my first instinct is to deescalate and move on. As said in thread below, if I have to draw my weapon I am prepared to use lethal force to end the situation. It is ONLY pulled from the holster or shown in the event that I have a valid threat to me or my family. I am not talking about protecting my car, wallet, watch, rings etc...I am talking about a threat to my or my families life. They can carjack me all day, take my wallet those things are replaceable and not worth me unholstering my weapon unless I feel the weapon they are pointing at me they will use it. Things can be replaced...people cannot. If I have to kill someone to defend myself or family then I can live with that.

If I have to Pull It out I'm Going to use i.t

I follow AR 190-14...

The law dictates ROE-simply stated, you, or someone else has to be in an imminent threat of death or serious injury (i.e. no pulling your weapon because someone cussed you out at the light, or backhands their spouse). For me, that means that unless I have a very reasonable (and more importantly, proven) sense that someone is about to shoot, stab, or bludgeon me or mine...my best option is to execute an orderly withdrawal. I think all of the, "if you have to shoot, make sure they're dead" crap is crap...the law is clear; once there is no more threat, you better stop pulling the trigger...whether that takes one shot, or ten. Bottom line: If you draw and shoot, you just signed up for some expensive legal bills, and probably some time in the lock-up. If you acted in accordance with the local laws, you will at least be alive...eventually free, and maybe have a decent defense against the scum-bag's attorney who's working for free to get publicity. Calm Down, Call 911, tell them What, When, Who and Where, weapon on the deck in condition four, face down, hands behind your head.

Well, drawing in public can be a crime in itself and just knowing you have what you have should help boost your ability to be firm and resolute. At night having a light would help too I want to get a blinky one (strobe). I think anytime you show or discharge a weapon it would be wise to inform the police to avoid answering questions, later on. That is a deterrent from waving it around, if it's worth explaining though it is viable.
Unlike the police or military, I'm not going for the lethal stop. My personal idea is to go for the unpopular shot to disable. I think shoulder or maybe some other spots. I wouldn't want to hit either main vein might need a tourniquet. If there was no way to stop an attacker after the first shot or enough information was known, than it would get ugly?
