One such argument says: Critics erroneously believe that anyone present in the United States has “subjected” himself “to the jurisdiction” of the United States, which would extend citizenship to the children of tourists, diplomats, and illegal aliens alike.
Here he mixes diplomats, who are not subject to our jurisdiction, with illegals who are subject to our jurisdiction.
The difference. As seen in the movie Lethal Weapon II, where the South African diplomat tells Lt. Riggs "You couldn't give me so much as a parking ticket."
Diplomats and the family and staff, are not subject to out tax or criminal laws.
Whereas illegal aliens can be arrested, indicted, tried, convicted, and incarcerated, just like any US citizen.. Just like a US citizen in Mexico or Canada is subject to the jurisdiction of their laws.
