The FBI may have enough to round up all the protest leaders on RICO charges.
Include the Rumpus Society, and all known financial backers, including Mrs. Kerry. Also, organizing and/or coordinating with groups that are known to be crossing state lines and international boundaries (some hate group in Canada is said to be coming here, the same group that rolled marbles under police horses' hooves in Toronto) with the intent to disrupt political procedings is a federal crime. And let us not forget that police animals are considered to be officers of the law like their human counterparts, so injuring a police horse is a serious crime. Just wait until some NYPD horse gets a broken ankle (God forbid) - there will be some serious baton action as a result, and I think most Americans would sit back and laugh at these scumbags for instigating it.
