When the 14A speaks of "jurisdiction" it means political jurisdiction not legal jurisdiction. The open borders crowd says it means legal jurisdiction but that is preposterous. Of course everyone in our borders is subject to the legal jurisdiction of america and it's states. To suggest that illegal invaders are free to commit murder is absurd.
When an illegal mother gives birth in america, the kid inherits her nationality and is subject to the political jurisdiction of that country, not america's. Case closed.
The real question then is what do we do with the millions of kids erroneously given citizenship because they were born in america to an illegal alien mother.
