"Wow. You're really going to minimize this as "some local law"?"
It's local to New York state. And I really don't see anything earthshattering in that law anyway.
The provision for background checks for buying ammunition is silly, as are the "assault weapon" definitions.
I am a supporter of magazine limits. I also don't think reporting people who are mentally unstable is a bad thing. Nor do I think reporting stolen guns is unreasonable. I also support secure storage of firearms, and this law is only intended to keep them secure from family felons and lunatics. I don't have a problem with heavier penalties for people using guns to commit crimes or for people who shoot first responders. I also don't think a 5-year renewal for a pistol permit is all that onerous.
I guess it's just a matter of perspective. For some, being asked to seal your box of ammo with a strip of Scotch tape is the same as getting your door kicked in and being dragged off to the Gulag in the middle of the night.
