I drive a fullsized GMC pickup, with a dent in one side, anyway.
If I had the green light, I would have taken at least a couple of them out....the arseholes!
Seriously, what could one cop do, except maybe attempt to ticket the one squid who crashed? Since they're jerks, the rest of them may have swarmed on the cop.......
Of course, if there were enough cops, and they attempted to stop the pack of bikes, and the bikes ran and caused accidents....it would be the COPS fault!
(Unless George Bush was in the state...)
