With all such technologies banned today, there is probably little incentive to develop better jamming technology that can be more carefully tailored.  But if at least some uses of jamming technology were allowed, there would be a market that could drive the development of better jamming technologies in the future.  So if the FCC’s concern were that today’s cell phone jammers caused unacceptable levels of unintentional interference to cell phone networks, that problem might yet be solved through technological innovation.

Lest anyone argue that once any use of jammers was allowed, the “cat” would be “out of the bag”—resulting in the disruption of cell phone networks by pranksters, criminals or even terrorists—let me simply suggest Googling “cell phone jammer.” It may not be legal, but Americans can already buy cell phone jammers.  The reality is that, without a global totalitarian state, or at least completely sealed borders (an impossibility), completely banning any technology is impossible.
