It's a "may issue" permit. That means they can take it away for no reason at all. They don't need "mental health" or medical records. Just because they feel like it is enough. NY'ers are peasants who can be disarmed at will. Pretending "confiscation is underway- citizen(S) told to turn in their guns" because of medical records is a bad joke. It's also untrue.
In this case they didn't mean to, it was a mistake. But in truth, they can do what every they want. They can keep his guns just because they feel like it.
NY'ers are subjects, not citizens. These laws need to be fought in court, in the voting booth, in the legislature and on the street. Any government agency that enforces them discredits itself as illegitimate. Anyone who submits to them is a peasant. All NY'ers have had their man cards revoked until these laws are overturned.
