He's right. You can't "close" the border. We need to work on inland security and make it harder to for people to live here illegally.
People got across the Berlin Wall, you'll never be able to lock down our entire border with Mexico.
Never? Are you OK with 25,000 M.E. illegal invaders coming in from Slamic nations the last 12 months? Unaccounted for, living here, invaded our borders. Never is not true (100% no, but 99.999998% yes), because if we applied 21st available technology to increase security on the NK/SK border, which we are so that we can leave, we can do it on both our borders. The question is why not try if we can possibly can. This whole can of worms ends up with people in America dead or having to see our blood in our streets. It needs to be addressed seriously as America's top domestic priority, not just winded at anymore.
