What creeps me out about the NYPD's "FOIL" nonsense and extraterritorial spying shenanigans (aside from the obvious 'New York is attempting to become a belligerent police state forever because terrorists' problem, compounded by their illustrious history of fine police work) is what the structural pressures on their hiring process must be.
So, a cop shop wants to build themselves a sinister clandestine intelligence acronym soup, combining as much of the overt menace of the CIA, the elastic jurisdiction of the FBI, and the panopticonic data-crunching of the NSA. Now, they don't necessarily have that in house, so they go hiring:
Trouble is, there are already actual federal agencies, with actual powers, and badges, and relationships with foreign states, and other neat stuff that a police department with delusions of grandeur notably lacks. What to do? One is led to the disquieting consideration that the NYPD's wannabe division either has some damned amazing salaries, even by the standards of people who can get the fed jobs that require clearances that you need clearances to know about and/or it may not...to put it politely... be hiring from the deep end of the talent pool.
If your options are 'Work for the FBI' or 'Work for New York's pitiful wannabe squad and associate yourself with its noble tradition of meddling in foreign investigations and being told to buzz off, the big kids are trying to work here..', which are you going to pick? Obviously Option #1, unless NYPD is offering crazy good compensation, or a dangerously long leash, or there is something sufficiently...substandard...about you that the real feds don't want you.
What kind of team are they assembling under those constraints? Best case, I'd assume its largely mercenary semi-retirees of federal agencies who don't have the juice for a career in lobbying; but can pull a nice paycheck for comparatively light work fluffing New York's ego.
Less good case? Well, a lot of B-listers who don't have any overt dishonor associated with them; but we can't all be astronauts when we grow up, now can we...
Even less good case? Even...morally flexible... organizations probably have to cull the fuckups, the troublemakers, the just-can't-finish-one-damn-project-without-a-diplomatic-incident rage cases, the people who keep the classify-and-bury stamps particularly busy. Now, where would a newly unemployed person with a background in fedding; but some slightly troubling paragraphs on the CV go looking for work? Maybe some creepy-as-all-hell private security firm, maybe a police department trying to buy its way into the big kids club.
What could possibly go wrong?
