The cop was aware that he was being recorded, at 1:41 he states
"gettin' this on film? Cause I am." His arrogance is the most disgusting
part of his behavior. The cop was changing lanes, merging behind the
bike, and did not expect the rider to come to a stop, an easy mistake
to make, but still a mistake. I get the impression that the cop expected
the rider to be aggressive, cut the merging car off, and close the gap.
Instead, he was riding conservatively and being polite to another driver.
