Several points to ponder:
1) Just consider the state of affairs when a police army simply decides to arbitrarily not enforce particular cases. I'm not talking about the discretion to not enforce X or Y laws - they still intend to do that enforcement - just not against those people already on the list. So if you have an outstanding warrant for X - you get off free. If your neighbor does the same X tomorrow, he catches a case. That is the sort of arbitrary power that defines a Police State and WRoL environment. The King's Law is not law, it is usually Tyranny.
2) Consider 'why' they want to issue the 'Amnesty' - because their Police State is so vast and effective at generating work, they have generated too much work for their current back-room operations (the courts, the processing, the jails to handle everyone who is in violation).
3) Consider #2 just a bit further. If you run a business, one of the best 'problems' to have is too many customers. Most businesses will expand in the face of more customers. Why isn't NYC simply 'growing' their 'business' to handle all of the new 'customers'? Perhaps the profit margins are too low to build more prisons and hire more admin staff to process the 'customers'? Or, perhaps - the fundamental laws of economy have reached that point where a parasitic business can't expand because doing so begins to impinge too severely upon the host - the host that pays the bills. If the latter has any merit, advocates for Liberty should have a little hope that the bureaucratic machine being funded by 'taxpayers' is reaching its breaking point.
4) Take special note of the quotes from 'Citizens' in the article. Good luck ever using 'reason' or 'logic' or 'common sense' to change their minds. They believe the 'criminals' are 'criminals' because they 'broke the law'. Breaking the law was the bad part - with zero consideration of the validity of the specific law itself.
Here's the piece.
