I see a possibility, here. It has to do with how someone’s name is *removed* from the list.
Say someone with a FOID (firearms owner ID) sells a gun to another person with an FOID. There is a good likelihood that both of them will be listed, for the duration of their FOID, as owning the same gun.
FOID cards last 10 years. Each card costs $10.
So the way to mess up the system would be to set up “round robin” gun sales, with the idea of having many people signed up as the owner of a single gun.
This would do much to complicate the State’s effort to single out gun owners for abuse or crime.
The state doesn't know which guns, if any, are owned by anyone with a FOID card.
