The fact of the matter is bounty hunters have no powers of arrest anywhere outside of the United States. The truth is Duane "Dog" Chapman as well as his son and brother are not only in violation of Mexican law, they were operating in violation of Reese v. United States, wherein the U.S. Supreme Court made it clear that a bondsmans or bounty hunters power of arrest can only be exercised within the territory of the United States". This is well known by skip tracers.
Chapman operated as a publicity-seeking loose canon rather than a professional bail bondsman. Since he is in violation of not only Mexican law but of Reese as well, I doubt there will be much help forthcoming from the U.S. government.
Reese, 76 U.S. at 21.
....and case law for the way we cowtow to the Mexis that zip aross our boarders?
I am of the lay opinion ... that we should thumb our noses at Mexico. Playing by the rules sucks if you're the only one playing by the rules.
