Don't never, ever try to beat the cops at their own game. The odds would be vastly against one.
This is so true. One genius killed his wife and tried to make it look like a bad burglary. Cops knew it wasn’t a burglary at the front door. The screen door was too neatly cut to have been a burglary. Another guy, a Mensa member, killed some of his neighbors using bismuth. Took the cops a couple of weeks to catch the Mensa genius. The Mensa member was upset at the neighbor kids cutting across his lawn so he poisoned the family.
