Just so we're clear here, before events were even reasonably investigated, the Trump administration aggressively, publicly declared the ICE officer justified in killing the victim which it also characterised as a "domestic terrorist". Then it took control of the case and decided no action would be taken against the officer. If I can remind you, you suggested the ICE agent has committed manslaughter. So it seems to me by your own reasoning, the administration has likely not acted in "good faith".
But ICE seems to be. If you judge all of the millions of people working for the federal government based solely on your opinions on Donald Trump, you would be reaching bad conclusions all the time even if you have an accurate perspective of Donald Trump.
The whole administration, outside of Trump, spends basically all their time keeping Trump within the legal lines. Trump says he wants something, and they find the legal methods to do it, sometimes with very obscure laws, and sometimes they just have to say no. Then judges rule on things, and they go through the whole legal process arguing it. You can guarantee that before invoking the Alien Enemies Act, Donald Trump said something like "can't we just send these guys away?", and someone told him they can't deport those with temporary protected status until 60 (i think) days after they revoke it, and then he was like "what if we just send them somewhere else", and then a whole team of people scrambled for a way to make that pass all the legal tests. You can rest assured that there are many things that couldn't be justified, think nuking hurricanes or just declining to certify the election, where people just tell him no.
I'm not here to tell you that Trump is personally pursuing good faith execution of the law, but there are millions beneath him who do that as their profession. If you look at this scenario as though ICE are doing the what they are supposed to, it all is very simple. Minneapolis has highly lenient policies on illegal immigrants, and they found themselves in the news based on migrants committing enormous levels of fraud, so ICE increased their enforcement in that area. That's really simple. The two women deliberately obstructed law enforcement, and were ordered out of the car to arrest them. None of this requires you to assume anything out of the ordinary.
When you start getting into explanations like "Trump sent his gestapo to terrorize the blue city", you quickly require thousands of people to be shameless Trump goons, and you've fallen into untenable conspiracy theories.
