Have you guys seen this?
The following video features raw and uncut footage of dangerous acts being performed by the Missouri State Highway Patrol on civilian motorcyclists. Road blocks, brute force, ramming, and pit maneuver tactics were used by the police in order to try and stop civilians while on their motorcycles. (while not all of these tactics can be seen here, they were in fact used)
This clip is a group of riders going down 370 in St. Louis for the beginning of the "2012 Ride of the Century" when police suddenly produced a roadblock and in turn induced panic among many of the motorcyclists causing the chaos and commotion that you see within the video. The riders were all clearly wearing their helmets, nobody was speeding, there were no stunters performing any tricks, and no laws or traffic violations were being broken to provoke the mayhem that law enforcement felt necessary.
St. Louis also has a "No roadside checkpoint or road black pattern based on a particular vehicle type" law that was enacted on 4/30/2012; it states - SB 897 - This act prohibits law enforcement agencies from establishing roadside checkpoint or road block patterns based upon a particular vehicle type, including the establishment of motorcycle-only checkpoints. Law enforcement agencies may establish roadside checkpoint patterns that only stop and check commercial motor vehicles. The provisions of the act shall not be construed to restrict any other type of checkpoint or road block which is lawful and is established and operated in accordance with the provisions of the United States Constitution and the Constitution of Missouri.
This video was shot by multiple people from many angles and they have begun to show up online, I will try and link to them within the description as I find them:
The following video features footage shot from a different perspective during the ROC 2012 ride of the infamous "Missouri State Highway Patrol roadblock". Certain parts will be played at an increased speed of 1000% to save for time.
