Only border control can stop this. Deportation is needed to remove the rest, no exceptions.
I agree. Anything that is done after they cross that border is liable to be "a day late and a dollar short". By then they've already had a shot at our kids and we only hear about the ones that get caught.
If they get past that border, it's our children that pay the price, long before they can be caught and deported.
It's also important that we rid ourselves of this "infection" before it gets any worse.
