“This wasn’t at the border, it is my understanding these checkpoints have been set up 100 miles at points within the border”
We have 2 here on I-5 and I-15 and the only problem is that they don’t operate them 24/7!
Not only that, but at the one on I-15, they pretty much just wave you through as you slow down when it is open. Only one time have I ever seen the BP there actually stop a car and detain people and it was done without incident.
