Indeed, gnu. That's what your neighborhood SWAT team is for, after all. When you're ready to go, just phone them up and say, "There's a maniac in my place! He's got a gun, and he's threatening to kill the whole neighborhood! Please hurry!"

Then just wait for them to arrive. I expect Chongo will resort to this one day when he gets too old to bust heads, romance dames, and drive fast cars.
