But the department certainly did take action against Schoolcraft. Last October several officers from NYPD's Emergency Services Unit (essentially a SWAT team) appeared at Schoolcraft's Queens apartment, threw him to the floor, handcuffed him, and had him forcibly admitted to the psychiatric ward at Jamaica Hospital. NYPD officials lied to hospital staff about Schoolcraft's condition, causing him to be held for six days against his will. Officially, the visit to Schoolcraft's apartment was prompted by an unapproved sick day. But that does not explain the show of force or the officers' removal of documents related to Schoolcraft's complaints about the NYPD from his home.
