I won't be surprised if the GOP justices eventually say that because Trump is in charge of federal and federalized forces - those troops can't be tried for any crimes by any state if the troops are "maintaining order".

My FBI won't investigate anybody for shooting the right people and my DOJ won't charge anybody."
