Advanced Tracking Techniques Re: [FedCom] Update: Unknown Frequencies

[gary]

A similar technique is used with bumper beepers. That is, if they can't 
keep a tail on the target 24&7, they reestablish the location first with 
a cell tower location, then DF the bumper beeper.

 From listening to this done, it isn't clear to me if it take a warrant 
to locate a phone. Obviously, to tap it needs a warrant. Well, at least 
it used too...
