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.
There’s a reason why the left always ridiculed the right’s fantasies of resisting the government with weapons.
I’ve never heard the left do that. That’s pretty much always been liberals. Unless you mean ridicule the right for claiming to not be bootlickers.
