8 USC 1324: Bringing in and harboring certain aliensIllegals, I assume you mean.
But you're right: that's not all he's doing. I am not a lawyer and all that, but it seems like he's committed all the required elements of a federal crime:
8 USC 1324: Bringing in and harboring certain aliens
I would say that the bigger problem is a lack of empathy.
Why do you think "unfettered entrance" is a problem?
In the case of a lot of the people coming in irregularly across the US-Mexico border - in particular refugee claimants from places like Guatemala - allowing them entrance is not only not a problem, it's a legal - and I would argue moral - obligation.
don't see application.
Unfettered entrance is a problem because:
1) Terrorists can come in
2) Drug cartels can come in
3) Criminals can come in.
Unfettered is a problem because if anybody can come in at any time, we would be a third world country. You have to have the capacity to assimilate and provide support.
That is why we have LEGAL immigration. It is our moral obligation.
