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.
Yeah. And feds could kill you in jail pretrial. Idk mostly held by sherrifs or what in fed cases, but cops are on their side.
