It was anarchist, that mingled in with the rest of the crowds, then went to split off and went behind dumpster, only to dress in black hoddies "caught on tape" and ohh, lets, see, guys under 22 that due to medical science, that say the brains are not fully developed and lack maturity "ever wonder why majority of criminals are in this age group?"
Anyway, most locals were appalled at the violence. There were of residence of the city that went down the next day to volunteer the clean up.
I think if there is going to be another celebration next time, keep it out of down town core and send them to a park with big tv screens!!
