These internment camps are a slippery slope regarding military presence in the country. The Governors will not send their National Guard.
If this happens the military better decide ahead of time what happens to those that make it outside the perimeter. Are they going to shoot unarmed people?
The reason the USA has Capture and Release is because it was the only reasonable answer to border crossers.
Shoot from the hip is not the answer. These policies and procedures were based out of legal studies.
Good luck.
