What happened to the good ol' days, like in the movies. A good old fashioned warning shot into the air. Now that would work much better than just aiming at a BG. A gun to some, is just a gun, but when they hear that BOOM!!!, they snap very quickly back into reality.
I know you can't do this, but wouldn't it be nice. The guy in the restaurant, the guy in the truck, many others. A shot into the air would definitely wake some BGs up.
I know, I'm dreaming.
