People expect a police officer or uniformed security guard to have a gun. In many places (not all), people going about their everyday lives do not expect to see people openly carrying guns who are not police or security.
I know exactly why they won't get harrassed. People have psychologically attached images with theories or ideas.
See a gun?
Panic.
See a gun held by a man with a uniform?
Safety!
I wonder about Armored Car drivers. I wonder if they have to make drop offs in places that are a no-no for LTCHs?
Armored Car companies have agreements with the treasury dept and others so we can enter areas normally no nos. Like federal buildings and it is always fun to enter the federal reserve bank, drive on a airport tarmac, banks, schools, and others.
But only your sheriff's policy. Indiana state law exempts police officers from having to get a LTCH.
