In America, they have tailgate thefts which I would have assumed to be thefts from the cargo bays of Pick-Up Trucks but actually is the theft of the vehicle tailgate itself. Fox News reported on it yesterday together with some statistics on cities, States and makes of vehicle most likely to be targetted and tips on how not to let it happen to you.

The Canadian car-site I sometimes delve into had this story last month. Apparently, this particular crime is trading in used (often repaired after damage) cars while pretending to be a private seller and not disclosing the history of the car. Although, if anyone repaired and then sold on the car they used to illustrate the story, then good luck to them:
Whatever motoring crime you decide to take part in, if caught, you may well end up before a judge.
And that judge may well be an expert on motoring crime.
