i'm not saying none. this is about the facts. to say you build a wall and we'll be fine, that is not really agreed with by many people in the border security business as i'm sure you know. they're not saying they don't need a wall, they're saying the wall is not the answer. >> i'd say this, the wall is the central intrastructural component that we need to build, and then the rest of it are things we need to add on as vibration sensors, sensors in the urban areas where they are tunnelling. out in the open desert they're not tunnelling like they do in the urban areas. they have to have ways to get rid of the dirt. we'd see that happen. we need cameras, night vision equipment, sensors. if we don't build a wall, they will continue coming across the desert and that's the way they bring in people that are criminals and are terrorists. you have those coming here that want a job in america. that's part of it, too. if we don't build a wall, we'll have the mess we have today.
