The VCCR does not make any such distinctions.
one more time, the minute men do not make arrests or detain, they simply report violations at x, y, z locations. But you already know that, guess it's just more fun to ignore the truth then to deal with it.
Does Mexico abide by the rules of the VCCR when dealing with illegals? IIRC, Mexico deports the illegals that they find in their country without any regard to VCCR regulations.
