We declare a State of Emergency and the PC Act is null. If that don't strike your fancy then you seize a 50 mile section of Northern Mexico and declare it to be a DMZ. Cross it and die.
...and no, I'm not joking. Mexico has waged war on US for decades. Be glad I'm not in charge. The International Community would be mourning the loss of Mexico City.
Learned a lot today about the PC Act.
SoE seems to declare it null and the Marines and Navy aren’t in part of this. Marines on the border and the Navy on the Rio Grand. I’m OK with that.
