Did you catch the story about Eric (the man who rides the bus) in Philadelphia and jams cell phone conversations.
Is that ok? Is that a violation? Is he being violated?
Where did he buy the jamming device?
Here’s one possible place to purchase
So is there anything wrong with a theater using this sort of device to keep people who leave their cell phones turned on? I can’t count the number of times I have been to an event, where it is just plain wrong to have a cell phone on, memorials, lectures, movies, etc.. It is just common sense, turn your ringer OFF.
So now in order to keep the peace, devices like this have to be created and used to keep it quiet for others.
