Although I sincerely agree that the data should be encrypted, is it really that easy to intercept cellular phone calls? I thought you had to go to considerably more effort than programming a scanner to pick up these transmissions - I don't know much about cellular phones, but I thought they hopped frequencies and so forth such that it was a real pain to listen in. Yes, it's really easy to monitor cellular calls. They only hop frequencies when you move between cells -- and most cop calls will be within a single cell, simply because most of the queries happen *after* they've pulled someone over. Things will change somewhat with the so-called personal communicators, since they'll use much smaller cells -- but the basic problem is still the same.
