You can't fire a weapon within city limits in most (all?) cities in the U.S.

And you don't own the airspace above your land, or airplanes and helicopters could not fly.

And you don't just shoot at anything in the sky when you're out shooting.

And civil courts exist to fine you heavily for this sort of behavior if it does occur.

Why don't you just shoot at UPS vehicles for driving down your neighborhood streets?
