So whoever organizes the next assassination will probably have the actual shooting done by (or at least ascribed to) some fringe type who can be dismissed as crazy (like the attempted assassins of Gerald Ford and Ronald Reagan) who will then be killed. The public will then be given an official version which directs their anger at the supposed crazy person.
Maybe they could pull that off with their allies.
But not with the vast plurality of American patriots.
Then the 'two can play that game' starts and rapidly spins out of control.
I don't know who wins, but I know, and they know, before the dust settles they, personally, will be dead.
