In Fall River, seven police officers began wearing body cameras this week as part of a pilot program that the department’s brass is hoping to expand.

Chief Paul Gauvin said he wants the rest of Fall River’s 200-plus police officers wearing body cameras soon.

The cameras, slightly bulkier than an iPhone, can be mounted on an officer’s chest to capture videos of everything from traffic citations to controversial arrests.

“We’re looking at it as a tool to help us,” Gauvin said. “We’re obviously aware that there’s a frayed relationship between the police and the public. I think it’s going to really help mend that frayed relationship.”

The department is still dealing with the fallout from a series of recent scandals, including the dismissal of two officers accused of filing false reports to cover up police brutality.

With the footage captured by the body cameras, Gauvin said, “we’ll be able to either confirm or refute claims that are made against police officers.”

The launch of the pilot program in Fall River brings the city’s police in line with a majority of urban police departments in America. The rest of Massachusetts, though, remains behind the trend. Gov. Charlie Baker’s administration cited data in December that showed just 10 percent of the state’s police departments had body-worn camera programs in place.

In Fall River, the mayor’s office reached an agreement with the police supervisors’ union earlier this month to expand the pilot program into a department-wide policy. Negotiations are ongoing with the city’s patrolmen’s union.
