Police use alot of psychology in their work, They're obviously using the 'sub culture "canyon racers" ' line to aggrivate people who are 'normal upstanding citiczens' and get them involved. It's a good strategy. However, being the open minded, unbiased person I am, I could easily wonder if the policeman did something 'above and beyond the call of duty', so to speak, to cause these motorcyclists to assault (defend themselves from?) the policeman. As the saying goes.. The possibilities are endless. None of us can make any accusations nor form opinions without knowing everything that happened. But, no matter what, physical harm was done to a policeman and the people that did it need to be found, and hopefully justice can be served.
