If you have the subject held at gunpoint, and he is compliant, I'd keep him there;...
Great, as long as he
remains compliant. But if he chooses to depart, don't even think about using deadly force to "keep him there."
Do what you choose, but understand that there is risk in "keeping him there" even if he chooses to remain. While your attention is focussed on him you could get shot from the back, side, or both by accomplices. Not for me.
Not to mention the risk attendant in the encounter with first responders....
If I had a BG cornered in my home which he broke into (whether or not it was burglary, murder, kidnapping or other violence as his intent, I always assume the worst, regardless what a "burglar" says), and he tried to escape THRU ME, I would take that action as a threat and do what I would have to do.
The principle of the castle doctrine is that if someone has broken in there is the presumption of a reasonable belief that imminent danger exists and that reasonable force can be used
to protect yourself. However, that presumption is rebuttable. If it should happen to look like an execution, woe to you.
"Escape through me?" Dangerous ground. You might get off, you might not. At that point you are talking about a citizen's arrest. Reasonable, non-deadly force except in a very few jurisdictions..... And unlimited personal liability except for a sworn officer.
I'm not talking about cuffing, wounding, or restraining a subject, if he attacks, I would retaliate, if I had him at a stalemate at gunpoint as the OP stated with 911 and LEO on the way I would not let him go.
Retaliation is unlawful. You may lawfully use deadly force
if necessary to prevent death or serious injury and, in many jurisdictions, to
prevent a forcible felony, but you may not retaliate.
Again, you cannot use deadly force to "not let him go" except in some jurisdictions and under very, very limited circumstances in those.
If someone was to charge a man with a gun pointed at him I'd see it as a violent attack. I don't care if the BG thought it was a bluff so he could escape, I would see it as an attack. What kind of man charges into a barrel of a gun, a dangerous one.
Okay then, Maybe others would see it your way after the fact, and maybe not. I wouldn't want to be in the position of defending my shooting of an unarmed parson who was heading toward my door. Even if you prevail, it could cost you more than you have.
Do what you gotta do. Dead men don't get to complain.
Ah, but they can! Have you ever heard of forensic evidence?
And maybe it's the effects of TV fiction made to entertain, but I do not understand why everyone seems to think that if he shoots, he will kill. Your shots may not prove fatal or immediately fatal. The man in Phoenix was shot six times, and is alive to file a lawsuit. I've read that about 80% of the people shot by handguns survive. Yes, you may have some real live testimony to contend with after all.
Also, how about earwitnesses? The 911 recording? What the neighbor or policeman saw from the street? Joe Horn was saved by the testimony of an eyewitness. Could work both ways.
I was merely responding to the other memebers opinions to just let the perp go. I am not a LEO, I don't shoot fleeing men, I don't cuff burglars, I do shoot violent intruders in my home who threaten the safety and security of my family and property.
The law in all states allows you to protect yourself and your family as necessary, and in many you don't have to retreat or provide any evidence of a threat other than that of an unlawful entry or attempt, sometimes with force.
Watch what you say and do about shooting someone to protect property, though--in forty eight states that would be murder, and in the other two there are thresholds of necessity and circumstance.
I've had two unlawful home invasions and one violent attempt. The gun saved the day in each instance.
I've never had to fire a shot. I've never spent a dime on defense attorneys. I've never had a perp's family come back to retaliate.
Much, much better that way!
There is a great deal of training available, some on line, and many excellent books. Worth the investment, in my opinion.
