Nobody can tell what he recorded, true. But the possession of tapes full
of random noise (note, this is not what is found on a blank tape!) is itself
highly suspicious. How would he explain it?
Remember too that it is almost impossible to conceal spying well enough to
fool careful surveillance, once the opposition is suspicious (if they catch
you photographing military maneuvers, they don't need to look at the film
to know what you were up to).
