Assuming I buy the "built-in, undetectable part of the circuitry" excuse - how would they do the same with an LCD/plasma screen? Last I checked, LCD screens aren't exactly two-way mirrors. There would need to be a camera, and someone would have found it by now.
As I mentioned before - the easiest way to remotely monitor a computer screen is via Van Eck Phreaking. Ummm. Allegedly.
