They never know what their looking at anyway. We're putting our trust in these people's computer knowledge? There has to be a way for computer manufacturers to scan an internal image of each new model they come out with. This image could be sent to the TSA. Write a program for the scanners to identify each image as a match. If anything at all is altered it would send up a red flag. I have to believe that would speed things up and be much more dependable.
