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.
As soon as you shoot one, they’ll be calling it in. There is no winning in that scenario
If ICE shows up at your door, demanding entry, you have no recourse. The law no longer protects citizens in their own home
Deadlocks, security (metal) doors, Window grates do.
