I have no doubt that the Black Hats can.....given time. I'm sure that the
Whiter than White Hats already have, as one of the transmission medias we
use is Radio and we are within the Radio Restricted Zones of both Memwith
Hill and Fylingdales. So I have no doubt that the signals have been fully
analysed and decrypted with the algorithms, and techniques being passed on
to so you will conclude that in my estimation CCTV in High Security Areas as
portrayed on film bears as much resemblance to reality as a Hollywood
portrayal of History.
