My friend from the Bloc was talking about agencies that may not have sent stuff in. I know from past experience that there are internal audits within those agencies to make those determinations. If someone didn't send you a fingerprint form, a C-216, you'd have no way of knowing if there had been a conviction. Typically there's an internal audit within police agencies across the country that should pick those things up.
