You’re confusing “jurisdictions”. That’s the court’s jurisdiction not the prosecution’s jurisdiction.
Yes, if the State of MN brings a criminal charge against a federal agent, the case will be removed from a State Court to a Federal Court.
But the MN prosecutor will be in the federal court prosecuting the case. The law that will apply to the case will still be MN state law.
It will be a federal judge, and federal court rules about procedure, but MN state law and MN state prosecutors.
No, you didn't understand. Poster claimed they would have to fight the feds for jurisdiction. You argued they didn't. Then I set you straight that they would have to fight for court jurisdiction.
Just parroting back what I've said then simply declaring I don't understand it (despite explicitly acknowledging the state charge would be tried in federal court) just looks terribly misguided when you lied with your smug quip "that's not how it works", when apparently you pretend as if you knew all along jurisdiction was relevant and would be fought over.
