Using wearable video cameras no larger than the size of a deck of cards, Burnsville patrol officers record every traffic stop, every call for help and every major crime from their own point of view.
In a world where everyone with a smartphone is a videographer, the police must adapt, said Police Chief Eric Gieseke.
"The reality is, if we're not recording ourselves, someone else is," he said during a demonstration.
A technology that's only become practical in the past few years, police body cameras that can cost as little as $299 seem likely to arrive at most metro police departments in years to come, even as questions linger about privacy rights, video storage and how and when the cameras get used.
Beyond gathering more foolproof evidence, the cameras have drawn fervent support from those who point to early studies that show the cameras dramatically reduce complaints against police and act as a check against police misuse of authority. If similar results occurred in Minneapolis, a city that's seen million-dollar police misconduct suits, the cameras would more than pay for themselves.
The idea of adding the cameras there led to a dust-up last week when three City Council members held a news conference promoting them, surprising Police Chief Janeé Harteau, who said more study is necessary. Even as the conversation got off to a muddled start locally, police departments nationwide have taken a strong interest in the technology.
At a national police conference last week in Philadelphia, body cameras were a hot topic of discussion, according to Scott Greenwood, a lawyer for the American Civil Liberties Union.
"It is crystal clear that this is the big accountability measure in law enforcement in this point in time," he said.
