What does the warning mean?

I recently bought my 66 Barracuda from out of state, and when I went to title it and register for a license plate, they sent a state trooper out to verify the VIN number. A 66 does not have the now standard 17 digit type VIN, the trooper referenced a book he had with him and crawl all over the car checking stuff. The trooper would not let me see the book, either!

so, I'm confused. a state trooper came to your home to inspect it? or did you drive it to the licensing office, and a state trooper came out of the office to inspect it?
Curious how other states do that sort of thing. I've heard some states are rather easy about titling. In Washington State we have to trailer it to the State Patrol Inspection Office to have it okey-dokeyed.
