> Militarized police would have no excuse

They'd have the same excuse they have now: https://en.m.wikipedia.org/wiki/Town_of_Castle_Rock_v._Gonza...

Then again, if they did change that and use military-style regulations, complete with desertion and cowardice rules, maybe the equivalent of military police (police police?) can stamp out corruption and violence against the public, in the same way that a soldier stealing supplies or deliberately harming civilians would be (should be) punished harshly by a military court.
