I knew a LEO auto theft person that was an expert on HD VIN’s
He and the local auto theft crew would go MC rallies and look at the VIN’s of HD’s visible from the street.
They confiscate a lot of stolen bikes and parts at MC rallies.
Yeah, I had a friend who prospected for one of the Outlaws’ cadet clubs and he had to be ready at any time of day or night to go heist bikes for them. Usually it was from people who owed them money, but sometimes just from people they knew who had stuff they wanted. Just not from other members of the Outlaws, or other clubs that paid the Outlaws protection.
