Hold on, guys. This absolutely changes the narrative.
We've been assuming this was the only interaction between Pretti and these masked agents. Under such assumptions, it's fair to say they were violent cowards and had a competence problem. In a fair world, we'd be looking at manslaughter charges.
However, if they were aware that Pretti broke a taillight and remembered that they broke his rib before, then it calls into question their motivation. Perhaps, they weren't merely incompetent cowards, but were exacting retribution when they executed him on his knees. That's 1st or 2nd degree murder.
The Reich-wing is scouring the Internet for videos of Pretti and anything on him, you know, like they do all the time to victims like Trayvon Martin and others....while ignoring any evidence they might find about perps. So, there's no info on the agents who did this. Are they the same agents who broke his rib? Are they the same agents who shot Renee Good in the face? They're allowed to be masked. So-called journalists aren't looking at this either and perhaps cannot because the government will accuse the free press of doxing.
All of this is not evidence of a "domestic terrorist" kicking a taillight, but just how much our institutions have changed as we move into fascism.
