In landmark ruling, Mass. Court suppresses data obtain from "Cell Tower Dumps"

In a first of its kind case, the Massachusetts Supreme Judicial Court suppressed data obtained from a "cell tower dump" warrant. As noted here: 

The SJC ruled Friday in Commonwealth v. Perry that police must get warrants before running tower dumps, which the court described as a relatively novel law enforcement tool that provides investigators with the cell site location information (CSLI) for all devices that connect to specific phone towers during a particular time frame.

The court also held that warrants for such searches can only be issued by judges and must include protocols for the “prompt and permanent disposal of any and all data” that does not fit within the purpose of the search.
