Please stay focused. The Bill of Rights protects everyone within the jurisdiction of the United States. If you choose to make the argument that it does not, proceed. As I mentioned earlier, I'll play the part of Justice Scalia. Convince me.
Really? So the "People of Mexico" are now the exact same, Constitutionally speaking, as the "People of the United States"? How remarkable...
How "one world" of you. Did you work for Kofi Anan?
Further, I would expect a home grown criminal, illegally crossing the border, and running from the LEO's to be shot at as well. In fact, it happens quite often. So where does that leave you? Really, trying to stick up for a criminal invader fleeing from the BP tasked with stopping him. What next? Saying we shouldn't jail anyone? That the cops have no duty to follow you if you flee the scene?
Utterly ridiculous.
