You need to be aware of your surroundings and the local culture, whether urban, suburban, or rural. Yes, I can think of quite a few places you might get shot at for aiming a camera the wrong direction.
Maybe there's a meth lab or weird cult on the property, or an illegal dope grow. Maybe they just plain don't like outsiders milling around. Maybe they think you're some kind of spy or Govt agent. I'm not joking at all. I've had some very close calls. Some places, even the law enforcement is hostile or involved in illegal activity. I've learned when I need to operate fast using MF gear, versus foolishly attracting attention using a slower view camera, which might get mistaken for surveying equipment.
I'm not going to take the time to recite specific personal stories; but I do have plenty of them. And I'm not going to refer to specific places, lest what I have said get mistaken for any kind of "P" statement. There are just certain things you shouldn't do as a photographer. Don't take a selfie beside a bison bull. Don't walk up to a grizzly bear and her cubs. And don't take chances with hostile or unpredictable drugged people.
