because it is quite literally a case of post-sandy hook "Muh Chillens! we've got a right to know where these people are since they're a danger to society!". NY law requires they register, and their permits are legally considered publicly look-up-able info like a building permit at a courthouse. they want to turn this into an online map again. after what happened last time, a bunch of people got robbed while they were at work(and that's googleable), so a state senator is backing a movement to deny them the records. they're suing to violate people's privacy and "access public records" to build an online map.

Because New York is like, one of the most corrupt states in the country.
