The second picture seems to be a fake. The arm angle doesn't look the same, and it implies that it was taken in a parking lot (not likely).
This reminds me of those cartoons they show you which depict how three razor blades "pull" the hair out while the last one cuts it...
But technology and misleading graphics aside, ultimately, I would prefer a good visual scan to a pat-down. Not only is the scan more likely to find stuff, but it'll keep the line moving along more quickly.
The best way to do this would be to have a long corridor like in "Total Recall" where people walked along and everyone just saw the image of their skeleton with any guns or knives. And to prevent having to hire security guards, you could put the scanners near each waiting area for the plane, so that each load of passengers could see for themselves who was getting on their plane, and with what.
