That is the question raised by the incoming Chair and Ranking Member of the Senate Judiciary Committee in response to FBI assertions that the agency is entitled to use a device masquerading as a cell-phone tower to intercept your calls and texts in public.
The Daily Dot explains the troubling technology at issue:
The Stingray is a wireless wiretapping device—generically known as an IMSI catcher [international mobile subscriber identity]—which, while masquerading as a cell-phone tower and transmitting intermittent signals, can deceive a mobile device to force a connection. Once this link is established, the data collected by the Stingray can be used to ascertain the identity of cell phone user, along with who, when, and to which numbers a call is placed. Further, the devices can be used to capture content, recording phone conversations, and even snatch SMS text messages.

I am no worrying so much about the government accessing my phone information.
I am more concerned about the government allowing a meddling corporation to get that access.
