re: #317 Backwoods_Sleuth
catalytic converter thefts got so bad here that our local scrapyards now require a vehicle title.
One of our clients owns a junkyard.
Catalytic converter thieves were taking pickup truck loads of removed catalytic converters out of his yard.
We cut open a catalytic converter, installed a battery powered GPS unit, Covered the hole with a disguised plastic plate (you’d be surprised how small satellite-pinging-GPS units have become), and placed it back in the pile.
Couple of nights later, the owner knew who, and where the thieves were.
