Everything aside, what Dog did was good for everyone. He helped protect Mexican women from a serial rapist and brought justice (not to mention peace of mind) to the American women Luster raped and beat.
I've a gut feeling this is about money and not so much about any laws broken. I don't have a lot of confidence in Mexico being honorable about their laws being broken. Maybe I'm sterotyping.
Might have been good for everyone but it wasn't smart. Filming yourself committing a crime (bounty hunting is illegal in Mexico) then turning that film into a TV show is a short path to nothing good.
American bounty hunters have done time in Mexico before, and Canada too, as far as they're concerned it's kidnapping. That doesn't mean this situation is a straight law and order thing, but it does mean there's a perfectly good legitimate reason for them to want to put Dog away. He did break their laws, and he did turn himself into a TV star with the footage from breaking their law. I hope Dog finds a loophole, or at least that his fears of what will happen to him in Mexican prison are wrong, but he did make this bed.
Any idea why Dog didn't get to collect? Was it to avoid problems with the Mexican authorities?
