In March 2007, a free speech and free assembly rally was held in Union Square to protest a new NYPD rule of dubious constitutionality instituting a permit requirement for any assembly of 50+ people on foot or on bike in NYC.
While the restriction would apply to any assembly of 50 or more people, it was enacted as transparent attempt shut down, harass or frustrate the Critical Mass bicycle rides that have occured monthly in Manhattan for at least ten years.
After the rally proper, a Critical Mass ride (accompanied by citizen videographers from the Glass Bead Collective and other groups) set out north from Union Square, only to be subjected to outrageous and illegal treatment by NYPD officers in Times Square under the supervision and instigation of Sgt. Timothy Horhoe.
Despite the numerous video-verified complaints of unlawful arrest and the numerous provably false sworn statements in police reports documenting the incident, the Civilian Complaint Review Board said in March of this year that they cannot act to punish the officers involved for their willful perjury.
