Why do the "victims" of such behavior feel compelled to engage in yelling, name-calling, and otherwise engaging the aggressor(s)? Video the daylights out of their behavior. Use the video to convince the cops - at the scene or later - to bring charges, or go over the cops' heads to the local prosecuter seeking charges be brought. Use the video in a civil suit for damages and costs.
But egg on the behavior?
Why?
I'm not known to be the calmest, coolest one in the county (or surrounding counties) but I've seen more than enough of what happens with that sort of behavior to know you stand a chance of having the whole episode labled as mutual combat. There's no joy when that happens (even if the cops don't use that phrase).
stay safe.
