Because it simply is not what the amendment explicitly says.
An amendment to it is what is needed for us to change it.
Only these people were NOT subject to our government's jurisdiction at the time:
1. Foreign- Diplomats, Ambassadors, and Royalty itself, with Diplomatic Immunity under international laws and their family residing with them.
2. Native Americans on Reservations with Treaties giving the Native Americans autonomy to Rule and govern themselves,
they have their own governing jurisdiction on their reservation with the Natives.
3. Foreign national enemies of war, and their family members (during wartime)
Everyone else was under our jurisdiction, under our laws of the land.
You are even now to this day, labeling these crossers, ILLEGALS....because under the law these crossers on our soil, are under our laws and under our laws, they are crossing illegally, no? They are under
our jurisdiction for them to be, so called illegals....
