Correction.
At the risk of hijacking the thread, it is the most damaging interpretation of a Constitutional provision that we have.
There was a brief period in history when sanity prevailed and the provision was not deemed to apply to foreign nationals, illegal travelers and foreign agents.
Consider this scenario: Achmed travels (illegaly) with a pregnant woman deemed his wife. His mission? Kill as many Americans as possible. If that woman drops a little Achmed at any time before or after the deed, most here on FR and most courts would consider little Achmed a legal anchor baby.
I stand corrected.
