If you happen to be carrying a loaded firearm when it happens, that firearm can go off.
Only if the booger hook is on the bang switch and the external safety (if present) is disengaged, at which point the muzzle was supposed to have been pointed at an intended target.
For the statistically improbable situation you describe to unfold, quite a few stars would have to align during a live fire exercise, you’re likely to be a participant or spectator of that exercise and aware of the risks. This is not something that would happen in most peoples’ day to day lives “walking down the street” unless someone is already doing something super illegal with a firearm (brandishing).
keep firearms away from people who don’t strictly need them.
Please define ‘strictly need’ for me, because the meaning is a variable depending on who you ask.
In my eyes, you don’t ‘strictly need’ a seatbelt - until you’re in a high speed collision. So you wear one anyways.
You don’t ‘strictly need’ a fire extinguisher - until you’re faced with a large fire. So you keep one around anyways.
You don’t ‘strictly need’ a firearm - until you are being met with deadly force from a person or animal, need to hunt, or need to control a pest for food security.
Those are all going to traumatize whoever finds you, and are otherwise uncomfortable ways to go.
Dignitas uses nitrous in their pods. Pretty chill way to drift off forever, so long as you ensure a means to get rid of the CO2 to prevent that ‘suffocating’ feeling.
