Well the MA court system notifies FRB and the local PD whenever a LTC/FID holder has "subsequent activity" (court appearance) at the end of each day court is in session. Unsure if arrests also trigger this but suspect that would be true as well.
When you do an eFA-10 (FTF) or via a dealer, it is doing an instant background check thru FRB (NICS is also independently done for dealer transactions).
So MA is way ahead of KY!
