Our founding fathers did not give the Redcoats due process of law to protect their right to life and liberty.

One did: John Adams, who represented the Redcoats who instigated the Boston Massacre. Because the rule of law matters he defended them.

So while I agree that the friend/enemy distinction needs to be drawn, there are traditional, civilizationally-important controls around the violence which threatens to be unleashed. There are forms of process and warrants for actions, especially violent actions, which are to be taken against your enemies-- and this is baked into the American Tradition. If you resort to unrestrained violence, you undermine your Causus Belli. You lose the support you'd have if you fought a Just War.

Sic pacem, para bellum.
