Well, here's what I saw
The guy driving and gal camerawoman chased down this guy. That's harrassment in most locals. He'd had enough, stopped his vehicle, and confronted his harrassers.
As he approached the two, he stiff-armed the camera-woman with his left hand, interrupting the video, then claimed the other guy hit him. There's zero evidence, even in the heavily jostled footage that he was hit. When the video returned, the guy drew his firearm, made what I consider false accusations, before bleeding off to his vehicle and leaving.
If I were a judge...
Based on this evidence alone, I'd hit the harassers with two counts each, one for tailing him, another for engaging him after he stopped (instead of taking the more prudent action of simply driving away). I'd also hit the gunman for assault (violent camera obstruction), brandishing (there was no clear and present danger for him to draw his firearm, aside from his obvious falsified report), and possibly for violating whatever local laws might be present with respect to actively engaging a potential threat. How about driving to the local police station?
On the other hand, if someone's following me like that, I'll find a defensible position while notifying 911, then engage them as necessary, preferably in a remote area, so as to minimize any innocent casualties. Not so if I'm in contact with police and they advise me to pull into one of their parking lots, at which point I'll simply duck and let them take care of the two IDIOTS who were harassing the guy in the SUV while filming.
What MORONS! I'm DANG glad they were charged with four counts while the other guy was only charged with two. They EARNED those charges.
