A lot of incompetence and malfeasance on the part of government agents would be revealed if that was publicly and freely available.
That said, for the past twenty years, I’ve always been able to call the local PD non emergency numbers when purchasing a car and every department was happy to confirm make, model, year and whether it was stolen.
I have had PD run a VIN on a 50 year old truck when the number on the frame didn’t match the door and title. He had to search each state individually. He just checked the surrounding states as there is no national database. That was maybe 2017.
We can’t manage to compile that information in one place? Really?
