I didn't read the thread.
I could've sworn I posted to this when it was first brought up but I guess not?
I ride with a pistol. More because we live in the area with many, many animals. If someone suspicious was walking close to me, I would immediately start pushing my horse around and making it look like he was out of control, telling the person to back off because the horse kicks
I've actually gotten people with that before. You get a horse who's responsive enough and you make them jump around some, it's quite convincing to someone who has no idea what the tail end of a horse looks like.
If that doesn't work, I'm going to pretend to get everything under control and nonchalantly take out my pistol and put a shot in it.
If they don't get the hint at that point, it's their own **** fault.
I have zero problem shooting someone if they threaten me (And if they threaten my horse they're dead without question). I have, on many occasions, watched drug dealers walk down the road into town and sat on my porch with my rifle just staring at them, absolutely DARING them to try something. Sometimes image is enough to scare people off.
And ya know. My 200lb great danes I have started riding with would deter them, and if they didn't, well..... I pity the poor creeper. I don't know one single command that would take a massive boar hunting dog off it's prey until it was dead.
