Okay, how about this? NY decides somewhere in the language they are going to enforce a special tax on owners of certain type weapons. They pass (or likely have already passed) a law, rule, regulation that asks for the name, address and et ceteras on anyone who purchased so and so. No, they don’t want the serial number; they’re just looking for tax information! Don’t underestimate these people! That’s what happened to the Jews in Germany.
Right, but they still cant use the 4473 legally for that. It would have to be infos given at the time of sale (or via owners of existing guns) by the FFL. Bottom line is they arent currently allowed exc for certain cases to access 4473s. Im sure they could find any number of ways around that.
