I don't believe it takes an Amendment to get rid of the illegals-born-into-citizenship problem. See, the 14th also contains the phrase "and subject to the jurisdiction thereof", something that could be established does not apply to those who criminally invade our country (and the spawn thereof).

Again, if one is physically present in a country, you are "subject to the jurisdiction of" unless you have diplomatic immunity. If not, then we would be helpless to do anything with them no matter what they did. If they are not "subject to the jurisdiction of" then we cant arrest them, detain them, or do anything with them - they are not subject to the jurisdiction of out nation.
Again, this clause is included so that US possessions are included in the clause, not just States.

Do you really want to write into the law that illegals aren't subject to the jurisdiction of the United States? Open the jail doors ...
