I live in a rural area in PA, and my family owns property with "no trespassing" signs. Unfortunately, these signs are ignored, and people ride their ATVs around the gate where I walk my dog. Sometimes people have sped by very fast and next to my small dog. Mr. Ayoob, I know you answer on the safe side of things, and wouldn't want to give advice to put anyone legally at risk. But honestly, if a quad is speeding fast next to my dog, it really irritates me... If someone is speeding towards me and/or my dog, I would like to know your opinion legally, what situation I could get into if I fired at their tires (I'm usually carrying an AR-15 or G19). What about if I aimed it at their vehicle (as a warning to slow down)? Consider a situation in that I could also be in danger, as well as my dog; the speeding vehicles do not slow down around the many curves and I could be killed. They are usually teenagers and enjoy passing at threatening distances. I have had to decrease my walks during "busy" hours when there are many trespassers. Usually when carrying the AR-15, they keep a distance but not always. The only thing I have done so far was yell, which hasn't worked. There is no need to mention the obvious about blocking off the property better; there is seemingly an infinite number of ways onto the property. When my grandfather was alive, he put a lot of money into blocking off the property with cables and cut trees and all that resulted was stolen cables and new paths. Clear "no trespassing" and "POSTED" signs do remain though. It is a losing battle that we have given up. It is a frustrating duty to patrol the property. Once there was a group of guys with shotguns who I asked politely to leave, and they refused (saying they were given permission by an adjacent owner, whose property was about 500 yards away). When I was walking away they fired about 10 shots.
