Australian Police Use Telcos For Cell "Tower Dump" of All Connected Users' Data 60

AHuxley (892839) writes The Sydney Morning Herald is reporting that Australian federal and state police are using a no warrant cell phone tower metadata access technique called a "tower dump". A "tower dump" provides the identity, activity and location of all cell phones that connect a cellphone tower(s) over time (an hour or two). The metadata from thousands of phones and numbers connected are then sorted. Australian law-enforcement agencies made 330,000 requests for metadata in 2012-13. AHuxley links to some U.S. views on the same kind of massive data grab: The Wall Street Journal says they caputure innocent users' data; the Chicago Police Department is being sued for information on its purchases of equipment associated with this kind of slurping; and the EFF asks whether warrant protection for users' data will be extended by voice-comm companies as it has been for ISPs. I wonder what people would think of an occasional "postal zone dump" employing the same kind of dragnet but for communications on paper.
