Generic bad guys who don't want the FBI tracking them.  The civil liberties 
types are suing the FBI to make sure the get a court document before they 
install GPS trackers on suspects cars.

Truckers who don't want their boss to know what they are actually doing.
The 
FAA test in NJ had troubles because of truckers using GPS jammers on the 
nearby NJ Turnpike.


There is also jamming from broken gear, perhaps broken by (mis)design.  The 
classic is a TV repeater on a boat that wiped out Monterrey Bay.  GPS World 
used to have a good article on-line, but the URL I had bookmarked is now
404. 
 Anybody got a working URL?
