One of the investigative tools in question is something called a “cell tower dump,” which allows law enforcement to get information on all the phones in a given area at a given time.
In two cases, Magistrate Judge Brian Owsley rejected federal requests to allow the warrantless use of “stingrays” and “cell tower dumps,” two different tools that are used for cellphone tracking. The judge said the government should apply for warrants in the cases, but the attorneys had instead applied for lesser court orders.
Among the judge’s biggest concerns: that the agents and U.S. attorneys making the requests didn’t provide details on how the tools worked or would be used — and even seemed to have trouble explaining the technology.
