Several people have baseball bats. At least one person has a gun.
So this was NOT a "spontaneous" event. Likely some kind of rumble that was planned.
All of the participants are black.
The caller/ videographer sounds like an adult black male, and he doesn't like what is going on, so he calls the police.
Nah, both voices are white southern boys. Probably service employees of some sort (maybe state or county) talking over their radios.
