Privacy groups raise red flags over police misuse of Flock cameras

Now to the growing backlash against Flock cameras. Those street and roadside cameras that snap photos of your license plate in more than 40 states. Law enforcement officials say they help solve crimes, but privacy groups are concerned they're being misused by police officers. Here's senior national correspondent Mark Strassmann. Ohio State troopers in pursuit of an attempted murder suspect. They captured his car on camera and that's how they tracked down and captured him. Across America, police agencies now rely on Flock surveillance cameras. It doesn't tell us who did it. It gives us leads that we otherwise would not have had. Flock cameras create a vehicle fingerprint, a unique high-resolution image of a passing car's make, model, condition, and license plate. This crime-fighting tool has also led to the arrests of dozens of police officers, allegedly for misusing it. Including North Carolina cop Elizabeth Snowman. She allegedly accessed the Flock system more than 30 times to track her boyfriend's ex-wife. It all goes up in smoke when you have cops like this violating the system. Block the Flock protesters see it as a tool for the surveillance state, including Taylor Arnold in Cobb County, Georgia. We don't have any option to opt out. You are driving, um there's seven within this intersection right here. Um it's not something we can get away from. Flock claims its cameras helped solve more than 1 million crimes last year and returned more than 10,000 missing people. Any level of abuse police abuse of their power is unacceptable. We talked to Garrett Langley, Flock's co-founder and CEO. When there's abuse, is some of the responsibility on Flock? We can't avoid responsibility. I don't think the tool is the problem. We have to find a way to be both safe and maintain privacy. Flock's technology includes audit logs and police agencies use those logs to spot people who are snooping illegally. But, whether any company can build a privacy setting that is absolutely foolproof is something else. Matt? Mark, thank you.
