No, not unless hired as an agent of the property owners. And the prevailing rule in self defense situations in any event is “you cannot shoot an unarmed opponent.”

Don't bet your life on it. If there is a great disparity in physicality, like a 250 pound young adult assaulting or battering a 100 pound elderly person. Deadly force could be employed by the victim or another to stop the threat.
And to further complicate that, in most states, if you accept payment for, or even extend the offer to provide armed security, you are required to be licensed through the state to do so.

Only in enemy occupied territories, in free states such as Texas you only have the believe as a reasonable person would that the aggressor means to cause you serious bodily harm, thats it the exact wording of the law. I got jumped off 6th walking back to my truck after a shift at the bar during college. Rounding the corner heading to my parking meter spot. There was a struggle I was a CCW at the time and got my boot gun a keltec P3AT in 380 fired it 3 times at belly button distance. The idiot bleed out before the medics got there he was “unarmed” except for trying to beat my head into the concrete. Mandatory grand jury review it was no billed after a 20 minute review. I carry that little P3 with me everywhere its my AMEX never leave home without it little thing saved my life.
Not true. The questions are innocence, risk of harm, and imminence. Getting chased by a mob with multiple people attacking you certainly crosses the line. When you avoid harming the unarmed, or the armed who are not yet attacking you, but only harm the individuals attacking you with weapons, or holding a pistol, that seems like a strong case for self defense.
