Happened in Las Vegas, cop rear ends the motorcycle and breaks out the scare tactics (threatens to write tickets) to get out of it. So i can see this video has sparked some idiots to come out of the wood work. The rider hit the brakes because a car from the left lane hit there's and was about to merge, its called defensive driving, and its important for all riders because people in cars do not see riders. Another thing, the biker did not slam on his brakes, he may have hit them hard, but at only a few MPH, it should not matter, the tires you heard lock up and screech were the cops tires. SIMPLE FACT IS; the cop was following to closely, and wrongly blamed the rider for the accident, using scare tactics to get out of it. The biker has said the reason he did not push the issue further was because he had just watch the video where an officer from the same dept, who shot a man 7 times, once at point blank.
