That feisty little detail about "subject to the jurisdiction thereof" is simply tested. A US citizen can be compelled to sit on a jury. A non-citizen can not be compelled or allowed to sit on a jury. Neither parent could could convey citizenship to their offspring. It is only an interpretation by SCOTUS of the 14th Amendment that has permitted birthright citizenship that was originally intended to apply to recently freed slaves. There are no persons living today that meet that special qualification.
I have thought “subject to the jurisdiction of” was covered by being detained, having your property confiscated, and being forcibly removed to a foreign country.
If illegal aliens are NOT “subject to the jurisdiction of” United States courts and executive agencies, just what does that phrase mean?
