A masked guy breaks down your door w/o an Article III warrant absent exigent circumstances? Yeah, I’d agree. Trick will be that pressing the murder charge would be federal since a federal agent dies in the line of official work (though illegal), which would give the president grounds to push for death.
Not true, though. We already have videos of people threatening to use 2A if ICE breaks in, and then of ICE leaving… In other words, you can scare them off. Do you think the average ICE agent wants to risk their own life to fuck someone up? No, of course not. They want to risk another ICE agent’s life, not their own.
