they are doing a shitty job of enforcing it. Illegals shouldnt be locked up in our prisons, they should get a swift boot in the ass back to whatever shithole they crawled out of. If that fails, we should just kill them. And to try and prevent them from getting back in, the borders need to be patrolled better and the people doing the patrolling should be allowed to shoot to kill anything trying to stick its dick across the border.
