Illegal alien not part of Second Amendment "people."

The Fifth Circuit (Texas, La., Miss) held that illegal aliens are not entitled to Second Amendment protection. The dissent raises some troubling issues, but, on first impression I agree with the majority as far as the Second Amendment goes. Although I haven't thought it out much, it seems to me that the definition of "people" must be read in the specific context of the specific right. On the other hand, one can argue that the natural law right, from which the Second Amendment springs, extends to all persons, in the U.S., citizens or not. I hope this case gets to the U.S. Supreme Court.
