Many, many years ago, when part of my job was commanding the police auto pound, I received a complaint that the police had impounded a stolen pickup truck, then released it back to the thief a day or two later. It didn't take very much checking to find the story was true to that point, BUT that the pickup was already once again in our auto pound.
This was a late model pickup that the owner had bought recently and never compared the VIN on the truck to his title. So, when he reported it stolen, he gave the officers the VIN shown on his title, but the actual VIN on the truck was one digit different. The thief was caught stealing from a construction site, went to jail with the pickup impounded, but he was only charged with the construction material theft, so when he got out on bond, he wen to the pound and got the truck. Then he got caught stealing again, and when I got the complaint about us releasing that truck, it was already back in the pound again.
ONE DIGIT difference in what was reported stolen and what was actually on the truck. So, as you might guess, I carefully check the VIN on my vehicles against the sales papers, the title, the insurance policy, etc.
