If you don't like what NYC is doing maybe you should lobby them? I'm sure they'd listen to you just as much as the current federal government would listen to NYC.
So you’re going to go to the police now with the information you have on your friends’/coworkers’ drug habits, right? After all, laws should be enforced, and everyone should proactively give any support they might be able to give to the police.
Sorry, but it kind of is. New York has decided not to proactively provide some information to a law enforcement agency. avocado4 is claiming that this is "trying to prevent enforcement". Obviously that is nonsense.
But it doesn't mean existing laws shouldn't be enforced IMO.
