In some cases, the actual content of calls can also be collected.
In 2014, the ACLU launched a nationwide search for police departments that own StingRays.
However, all their efforts started because of Rigmaiden, a convicted felon serving time in an Arizona prison.
Daniel clearly was a criminal.
And he believes the technology is wrong.
And that its wrong for the public, says Knappenberger.
Rigmaiden felt there was a serious privacy breach happening while most people he contacted figured he was a lunatic.
This is straight-up paranoid conspiracy theory stuff.
As a privacy advocate, Soghoian was shocked.
Theres no way to use it like a scalpel, he says.
Its like a huge trawler net.
This is a technology that scoops up information about mostly innocent people.
In 2014, after 68 months in custody, Rigmaiden pleaded guilty and was released on time served.
He became a passionate privacy advocate after his release.
In 2015, he assisted the ACLU in making a tutorial on how defense lawyers can contest StingRay use.
In the end, Knappenberger says the film is about an unlikely hero for privacy rights a hacker-criminal-turned-whistleblower.
The guy is on a mission, says Knappenberger.
Hes on a crusade to end this technology.
And the direct benefit to him has long since passed.
