According to an article I read on Breitbart, the gathering of bikers in the restaurant consisted mostly of above-board people, except for the Bandidos, which the umbrella organization holding the event apparently invited. Another outlaw gang, the Cossacks, crashed the event, and that’s when the fight started.
Bandidos and Cossacks are noted 1%er type thugs.....invited or not running with ether one is a sure way to end up with bad things happening
