Well, the cop probably didn’t expect that to happen… On this episode of cops! The cop was provoking him to do the wheelie, or at least that’s how he saw it. When he did it he came after him. It could be for some unrelated issue maybe something on his bike was illegal, but he wasn’t waiting around to find out. You can probably tell what city this is because it’s on a pretty memorable strip of road. The cop turns on the lights, and he questions him in disbelief right before he flips him off and disasters into the traffic.
