Welcome to OpenCarrydotorg (OCDO)!!!!
Over people relieving themselves on your property?
No offense, but I think that using a gun to plant the seed of worry about potential lethal force is a bit strong.
Only if you really thought there might be trouble. And then it would be hard to argue that you could not have avoided the lethal force confrontation if one occurred and if avoidance is part of your state's self-defense statutes or court opinions.Carrying a gun, shall we say ostentatiously, to discourage misdemeanorsand so forth is not really thebest approach.
I'm thinking it would be better to take it up with Lazerfest that they need to provide restroom facilities.
Then put up signs saying police dogs are on hand to sniff the waste for drugs. I'll bet most of your problem disappears on the spot, while throwing business to the local filling stations.
