I watched all of the reasonably available video of both the Alex Pretti and the Renée Goode killings. The descriptions you provide for both are just so wildly uncoupled from anything that can actually be seen in those videos that I wondered if I was losing my mind because I couldn't see what you said was "all on film from multiple angles."
After a quick sanity check (my Magic 8 Ball answered "My reply is no" to "Am I losing my fucking mind here?") I realized that your descriptions were derived not from the content of the videos directly, but passed through some intermediate process wherein you just described some alternative facts that agreed with your world view.
Were either or both of these dead people professional agitators? Probably not, but even if they both were, the guys who killed them did not respond in a manner consistent with their trainining, their agency procedures, or governing laws. The people who put those ICE/CBP agents in that situation, the current administration, will protect the shooters as long as it doesn't cost them anything, but a lack of consequences for doing the wrong thing doesn't mean it was the right thing.
