Actually, I will say something, this is an excellent area of discussion.
For the last 5 years I worked in a prison. Man, do those guys in there have cell phones. We couldn't keep them out. I think every prison should have a cell phone jammer tuned to jam signals within the prison. I realize this will extend out beyond the prison but this is something they can work on. Many low power jammer antennas within the prison perhaps. Someone has the solution. Of course, land line phones should be made available, free of charge to staff and visitors.
Other than prisons, I can't think of anywhere else right now. I want to say movie theaters, but that's probably not a good idea, too many bad things happen today.
