If so then we should post guards with orders to shoot anyone trying to cross at uncontrolled entry points. The death toll would probably be less than those who die from exposure now since the number attempting to cross would immediately and dramatically drop. Just how serious are those complaining about illegal aliens about coming up with a really effective solution? Sending them back doesn't work. We can't afford to jail them. If we are serious, there is only one way to do it. We have to be willing to "guard" the border for real.
