I see real issues of firing warning shots in an urban or suburban setting. Namely, the bullets go somewhere. I’d not want to accidentally hit a neighbor, their children, the car windows or their dogs.

If I am threatened enough to need a weapon I don’t think a warning shot is appropriate or needed. If I am just warning someone to get off my property there are probably better ways to do do that.

Can’t you see North Korea from your house?

Fire a warning shot INTO THE GROUND. That way it won’t go through the air and possibly hit someone far away or in their house.

This is old common sense information, but today, too many people have no common sense.

"I see real issues of firing warning shots in an urban or suburban setting. Namely, the bullets go somewhere."

Absolutely correct.

This story is from the Chicago Tribune just a couple of weeks ago.
"Celebratory" gunfire into the air does come back down.
In this case, fatally.
