Well, if he was involved in a mailbox dispute, send a posse of Feds in there and execute him!
Sadly, the FBI has been acting like the gangsta arm of the DNC, and doing all sorts of unethical/illegal activities, so it is not unreasonable that citizens might mistrust or even fear the weaponized FBI just as the KGB or the Gestapo was.
Of course, the FBI might only have been doing its job...could have been the guy was plotting to move at 6:15am, the mailbox 12 feet to the left of its current USPS truck-convenient location. Which of course justifies the need for a full FBI special weapons team, ready to deliver deadly force to protect the borde...er, mailbox location.
