I’ve written previously on this blog regarding stingray devices: powerful surveillance tools which allow law enforcement agents to spy on the cell phones of unsuspecting Americans, often without judicial or legislative oversight.
For a deeper dive into the subject, I’ve put together a policy analysis detailing the past history, present issues, and future prospects of stingray devices and police surveillance more generally.
From the executive summary:
Police agencies around the United States are using a powerful surveillance tool to mimic cell phone signals to tap into the cellular phones of unsuspecting citizens, track the physical locations of those phones, and perhaps even intercept the content of their communications.
The device is known as a stingray, and it is being used in at least 23 states and the District of Columbia. Originally designed for use on the foreign battlefields of the War on Terror, “cell-site simulator” devices have found a home in the arsenals of dozens of federal, state, and local law enforcement agencies.
