[discussion of laser eavesdropping]

	Well, this discussion is getting pretty interesting (2d analysis
of interference patterns?) but I think that we are all missing something.
	The fact is that this technology exists, or at least I have
been led to believe that it exists by several tv shows I have seen.
I have seen several documentaries on the growing ease of invasion of
privacy, and all have mentioned and shown the laser eavesdropping at
work.  
	The user shines the laser on the window of the room to
be bugged.  A dot of laser light does illuminate the opposite wall.
The listener listens through earphones connected to not very much
electronics (it looked like smaller than a shoebox).
	Maybe the shows were making this up, but they appeared to
actually be able to do this, and I am not technically incompetent.
There must be an easier way than what has been discussed.
