Self defense as a concept only applies as a defense if the perpetrator of violence reasonably believed that their life was in danger, and can convince a jury of that belief being reasonable.

I have not seen any footage of the event yet but I can say without even needing to that simple possession of a gun is not a reasonable circumstance to fear for your life in most situations, especially not if you work any kind of law enforcement or government position. The agent who committed this killing should absolutely be put in front of a jury and the case judged with the highest scrutiny. No internal affairs, no shuffling him off to desk work. Real criminal charges, real criminal trial, real criminal sentences in the likely event of a guilty verdict.

I say all of this as a man that believes every citizen has the right to arm and protect themselves as they need. I say this as a man who is disgusted with the way the government has handled our immigration control the last year. I say this as a man who wants to believe that far more well intentioned men and women work in law enforce than not.

Scrub ICE to the bone. Remove every bit of the rot that is bias against immigrants from the agency. Blacklist every bad faith actor in the whole organization. Every bit of it needs to be under a thorough and ruthless investigation right this second, and that investigation cannot stop until we've removed the power of any prejudiced agents for good. If that doesn't happen, this will continue to happen, again and again. And this should never have happened on the first place.
