The Constitution was explicitly a secular document.
On topic, they're apparently letting these idiots come and go as they please. On the one hand, I'm mad that they're letting a bunch of criminals operate with impunity, on the other hand, I can see the reasoning. If they block the roads, cut the power and phones, and start a standoff, that gives these toy soldiers exactly what they want, and increases the chance that someone will die over stupidity. Ignoring them seems to be the way to go right now. Once it becomes apparent they're not gonna get their shootout with the government, they'll get bored and go home. At that point, the feds can pick them up if they feel like pressing charges but really, what's the point?
