Its a criminal offense, I call in my car has been stolen and LE finds it.How so? If the thief has a BOS that would have similar need to be looked at in a civil court to verify authenticity.
Thief shows LE a Bill of Sale, Policeman Laughs.
Car is titled and registered to me, not the thief.
Thief doesn't have a signed title to go along with the Bill of Sale.
Thief goes to jail.
