Yea it’s as simple and stupid as that. This (black) peasant isn’t respecting our authority and higher status. If we let one slide then everyone is going to think we are equal to them. In their logic, they have to fight in court.
This is a common archetype when people get challenged (escalation of commitment), they effectively double down. I don't necessarily think it was racially motivated (but also don't doubt that it could have been).
Growing up Adams county myself, I'll go ahead and be the one to tell you that it was absolutely racially motivated. You do not want to be a minority out there. Hell, you don't want to be perceived as being left leaning at all out there. This is the same area where a ~15 year old girl was assaulted on camera, in front of a police officer for participating in a protest (IIRC, BLM, but I could be wrong). This made the front page of reddit when it happeend.
And this is very likely, corruption motivated as well. I have enough family and friends left out there who have first hand experience with the politics and policing of the area to know. In fact, I have a late friend who had this exact thing happen (though, one county over), on video and everything. He's just not a D list celebrity with money, so nobody cared.
If someone wrote a documentary about this area and tried to pass it off as fiction, people wouldn't believe it, as it would be considered too absurd to be believable.
