How about seizing NYPD assets and calling in the National Guard after removing everyone, collecting their data in a massive database so that they get blackmarked wherever else they would go for employment? I guess there would be an inherent risk of such a draconian policy, considering it was the American MO in Iraq, but then again, that's Iraq and this is America. Just a thought.
And, they're really badly equipped to do everything NYPD does.
