This is the 78th Precinct, which has a long history of harassing cyclists at Brooklyn Critical Mass events. This sounds, judging from the unmarked car, to be the work of Community Affairs Officer Jerry. You may call him at (718) 636-6410 to voice your concerns over the treatment of cyclists, and come out last Tuesday of every month at 7:30 p.m. at the 78th Precinct station house (6th and Bergen, 4th Fl), for the Precinct Community Council a "non-partisan group which meets with police officials to exchange mutual views and seek ways to solve local problems."
