A summary of Schoolcraft's ordeal can be found in the Wikipedia article about him:[1]

"After voicing his concerns, Schoolcraft was reportedly harassed and reassigned to a desk job. After he left work early one day, a SWAT unit illegally entered his apartment, physically abducted him and forcibly admitted him to a psychiatric facility, where he was held against his will for six days."

But Schoolcraft was expecting them to do something like that, and was able to make a recording of the entire incident.

It seems that the NYC police have adopted the Soviet practice of using the psychiatric system as a weapon against their enemies[2] (which happened both to Schoolcraft and the author of the posted article).

So The Wire basically had it right, they really do just play a numbers game? Comforting.
