The article from the OP was referencing the comments of a judge in Texas.
""He's going to try to hand over the sovereignty of the United States to the U.N., and what is going to happen when that happens?," Head asked.
"I'm thinking the worst. Civil unrest, civil disobedience, civil war maybe. And we're not just talking a few riots here and demonstrations, we're talking Lexington, Concord, take up arms and get rid of the guy.
"Now what's going to happen if we do that, if the public decides to do that? He's going to send in U.N. troops. I don't want 'em in Lubbock County. OK. So I'm going to stand in front of their armored personnel carrier and say 'you're not coming in here'.
"And the sheriff, I've already asked him, I said 'you gonna back me' he said, 'yeah, I'll back you'. Well, I don't want a bunch of rookies back there. I want trained, equipped, seasoned veteran officers to back me.""
I don't see "militia" mentioned at all. I think he is referring to the public being outraged and taking up arms.
