Take care of them the old fashioned way.
Make it a world wide Super Bowl level event—and feed them to the lions in front of one hundred thousand screaming fans and live television coverage.
If anybody is stupid enough to go there after that repeat once a month.
Yes! Wasn’t there some precedent for feeding them to the lions only 150 miles south of Florence?
Ive got a better idea. Helicopter them to the top of any nearby 1500’ plus transmission tower and have them climb down. No safety gear, as they probably wouldn’t knowmhow to use it anyway. For exta lulz, a drone will randomly appear and apply an electric shock. Have the two guys from American Ninja Warrior call the action. Put it all on pay per view.
