This would be something neither JJ or any of the other black fascists would want to be doing to my new truck. They might get away with this kind of crap in big cities in the north and in California,but if you try this down south you will end up wearing somebody.
The point I am making is that this is a tactic intended to cow and intimidate. I'm not saying it would with certain people such as yourself, but you know as well as I do that some people will think twice about driving into a NAACP 'roadblock'.
The language they use ('border patrol') suggests to this reader an aggressive stance. They know what this is as well as anybody.
