Heh, that made me remember a story from an uncle that was a PI/bounty hunter and ex-security chief of a (state that borders Mexico) Governor. He entered Mexico and captured a bail jumper and had a little problem re-entering. Seems like the Mexicans aren't real happy when they find an American in the process of bringing a handcuffed Mexican back over to our side.
He was glad that he had memorized a phone number of the Governor, and after a couple of tense hours, he was allowed to cross without his prisoner. I don't think he went back to Mexico after that, at least for business purposes. Heh, learn something new and remember something old every day I guess.
Or: seems like the Americans aren't real happy when they find a Mexican in the process of bringing a handcuffed American back over Mexico.
