What place are you referring to where drawing a gun on a person would be justified, but holding them for the law wouldn't be?
I've heard of neither criminal nor civil action against such an action. It may have happened, but where?
I don't know if it has ever happened or not. I do recall a story posted here by someone about a guy holding illegal aliens that were stealing or killing his sheep. When the cops came they arrested the OWNER for kidnapping. True? I don't know.
What I DO know is that in the class I had to take to get my carry permit we had a Q&A with the county DA. He told us in no uncertain terms that our rights to carry is EXCLUSIVELY for protection and that ANY use beyond that, mentioning specifically attempting to hold or restrain the BG, would result in charges against us. The only exception is under NY law which allows for restraining or even shooting a BG who is not a direct threat but has committed certain crimes.
35.30(4)-
"4.
A private person acting on his or her own account may use physical
force, other than deadly physical force, upon another person when and to
the extent that he or she reasonably believes such to be necessary to
effect an arrest or to prevent the escape from custody of a person whom
he or she reasonably believes to have committed an offense and who in
fact has committed such offense;
and may use deadly physical force for
such purpose when he or she reasonably believes such to be necessary to:
(a) Defend himself, herself or a third person from what he or she
reasonably believes to be the use or imminent use of deadly physical
force; or
(b)
Effect the arrest of a person who has committed murder,
manslaughter in the first degree, robbery, forcible rape or forcible
criminal sexual act and who is in immediate flight therefrom."
He also made a special note that the "robbery" justification is not "attempted" but actual. In other words, some guy walks into my shop and says "Give me your money." I pull my gun and he runs, I can not shoot him. If one of my people gives him the money while I'm out back and I see him when I come up front I could, technically, shoot him. I wouldn't but I could.
To confuse matters there's also the law regarding trespassing which does specifically allow the owner to detain the trespasser, by force if necessary.
