100 naked body scan images leaked; Why is scanner picking up people in line?

Fortunately, this was the lesser intrusive scanner, being used at a courthouse, that jumbles up the photo so as to hide your genitals, etc.  But I did notice something weird.  Why does the scanner seem to be scanning people who aren’t even in it?  Note how the device is recording the image of people standing in line to get into the scanner in the photos below.  They’re not in the scanner, but it’s picking them up.   It even picked up the security guy with his wand.

And, as a reader just noted, I’m sure there’s no radiation leakage from a device that can pick you up from ten feet away.
