Correctly (for a change), the media calls this pack of assholes "bikers." As usual, this is more evidence that groups of young men should never be allowed to congregate for ANY reason. As far as I'm concerned, it would be perfectly reasonable for the cops to fire a couple of shots to the head to get the attention of this bunch of morons. You do have to wonder where New York's finest were during all of this? I'd bet the guy in the cage was dialing 911 constantly asking the same thing.
There is another hour's worth of gangbanger video here, just to emphasize how unlike a "family ride" this "event" was. Pretty much any commuting motorcyclist has been put at risk by this bunch of assholes: http://oppositelock.jalopnik.com/first-off-has-ray-kelly-said-anything-about-this-gang-1437209127.
