I like your approach, but it lacks a deterrent effect. When a bookie rubs out a deadbeat, he may lose any prospect of being repaid, but he discourage deadbeats, but only if the circumstances of the deadbeat’s demise are widely known. It’s not just D’Shawn that you need to worry about, but his cousins, and bruthas.
So, anonymously send D’Shawns head, in a Fed-Ex package.
Maybe a brutha or a cuzzin will open the box.
