I can imagine the outcry the first time one of these jammers prevents someone's 911 call from their cellphone in a situation where they could not get to a 'regular' phone.
If you are in a movie theater and need to call 911, use the land line. It isn't like there aren't hundreds or more people around to assist in making the phone call.

I agree that any attempts to use this for things like movie theaters will definitely have some major hurdles to overcome.
