This clip, shot right before Patriot Prayer arrived at Cider Riot on May Day, is the clearest evidence I've seen supporting the claim that PP & leader Joey Gibson were intent on instigating a fight that afternoon.
On video, Andy Ngo laughs and follows along as PP members plot out how to spray people without hitting themselves, brag about their various weapons and say they're "prepped for war," declare "there's gonna be a fight," etc. Seems like that'd be newsworthy?
