bing l, the former chief of staff of border protection. what did we get for our investment, thad? is. >> well, jon, people shouldn't view this as a cancellation in any way of putting technology out of the border. a lot of the technology that's out there and has been put out there and will continue to be put out there was not part of this project under boeing. what did we get? we did get some towers with the sensors and some integration in those 53 miles, but a lot of it you can't necessarily see. a lot of it was the software development and research and development that went into the back end of that program of learning how to integrate those sensor feeds, learning how to display them in a common operating picture. so it's not all money down drain. in fact, a lot of this will be used going forward. jon: but didn't we learn that it doesn't work? >> we learned that it does have problems and a tower-based solution isn't applicable everywhere along the border. many of the miles are different, many of the terrains are different.
