US authorities are warning wannabe vigilantes against taking the law into their own hands after an armed militia group detained over 300 migrants earlier this week at the Mexican border in what they claimed was a citizen’s arrest.

let's get this straight - they detained them, called authorities and are now called vigilantes?

Who benefits from our militia being treated like criminals?
