Honestly? Nearly a decade of working contract security, including most of that time being level 3,
I can easily say that I’d rather not be armed.
First, carrying visible weapons makes people respond differently. They see you’re armed and everyone reacts to it. Its mere presence escalates situations.
Secondly, your very question implies the trap always being armed leads to- you assume this man is aggressive or hostile. And most often that assumption is flat wrong.
When all you have is a hammer every problem looks like a nail.
Finally, situation awareness is infinitely more valuable than any weapon. You lose every fight you get into. Even if the other guy doesn’t harm you, if you draw down and shoot, you’re going to jail. You’re going to be held until they know what happened, and you’re probably getting charged.
You lose on legal fees. You probably lose your job. And now you have to live with guilt- even if the subject had it coming.
Also just a side note I was discussing open carry. Concealed is a different matter; concealed properly, no one will know until you draw. (And then things escalate fucking fast.)
