Minneapolis police are about to join a growing number of cities where officers are testing the use of body cameras, a move that leaders hope will force police and citizens to be on their best behavior.
The change is raising tough new questions about how the cameras should be used at a time of growing public and political pressure for more accountability during police stops.
Mayor Betsy Hodges is encouraged by the potential of the new technology, but wants to make sure they are thoroughly tested before being implemented more widely.
"Just like anything else, you can't simply overlay the policies and practice of one city or state onto Minneapolis," said Hodges, a leading supporter of the body camera initiative. "We're our own unique city with certain dynamics and political makeup and community relationship that's different from most places."
A Minneapolis City Council committee gave tentative approval Monday to buy $170,000 worth of cameras and equipment for the test program. Final council approval is expected Friday.
The cameras can be clipped on eyeglasses or onto the front of a shirt and are intended to capture an officer's interaction with the public, providing potentially critical evidence in any dispute.
Cities and police departments are trying the new technology at a time of renewed and intense national focus on police accountability after the fatal shooting in August of an unarmed black teenager in Ferguson, Mo., a suburb of St. Louis.
Minneapolis has paid out millions of dollars in settlements for alleged police brutality and endured dozens of misconduct lawsuits filed against the department in recent years.
