We don't disagree often, and drone's observation above began nagging me. So I had a re-think, to see if and how I'd maybe gone wrong. And it hit me: broadband vs narrowband:

To operate a communications device (almost) anywhere requires a license from a gov't agency - including American CB radios, until the late 1970's when our FCC suspended CB licensing due to being swamped by applications they hadn't the manpower to process. But the point remains: if you're gonna broadcast to any and all receivers on the public air, you have to be authorized to do so, to insure transmission competence, and impose fair usage user rules of that public asset. No expectatyion of privacy.

Cell phones require no such licensure, because the transmission is narrowband, intended to establish a transmit-receive transaction from a single device to another single device, not broadcast to the entire world. Thereby implying the 'expectation of privacy', thereby invoking the 4th Amndmt protection against unreasonable s&s.

Law enforcement therefore must get a 4th A-over-riding warrant from a proper judicial authority to monitor either actual traffic or even the existance and location of a device.

In other words: I was wrong, and am now against warrantless searching of cell phone records, locations or transmissions.

Thanks fellas, for entertaining my objections.
