No distinction was made between “legal” and “illegal.” Those here are completely under our jurisdiction. We have tried and executed illegal aliens for murder. You don’t get more under our jurisdiction than being executed. At the time the 14th was adopted, there were only three exceptions. Children of:
- foreign diplomats
- Indians on Indian lands
- occupying forces
No other exceptions. And if one understands what it means to be under our jurisdiction (subject to our laws), you’d understand why those three are exceptions and nothing else.
