Lex's blog post on the subject is worth perusing.
I suspect it's going to be tricky sifting fact, from fiction, from tin foil hattery.
In any case, this 2nd Amendment post is a couple days late but perhaps apropos of the weekend's news.
"The militia, sir, is our ultimate safety. We can have no security without it... The great object is, that every man be armed....Everyone who is able may have a gun."
Methinks, the problem isn't too many of these militias popping up and creating a stir.
The problem is not enough people involved in the militia.
More involvement in militias would necessarily involve more folks from a broader cross section of society. That would dilute the influence of cultlike thinkers and personalities in militias. The result would be a moderating and mainstreaming of the militia.
