i was wondering why "the washington post" did not focus in the story on how smugglers are getting into the country illegally. isn't that the point? whether they're using saws or anything else, is the point that they're getting in illegally somehow or that the wall's not perfect? >> look, the wall -- no walls are impenetrable, and we've said it from day one. the wall slows people down. and so when they made the six prototypes, they came up with the system for a couple reasons. one, they can see through the it. and second of all, when a ballard does get cut through, it's easily replaceable. the bottom line is, ed, the new wall's working. till legal crossings, wherever our wall is built, is down. the drugs are down. to the wall's slowing people down. that's why they talk about a wall system, you need the technology so if someone incurs it, you're going to get sensor technology, and plus the resources to respond to incursion. i'll say it again, the wall's about slowing people down,
