MINNEAPOLIS — Minneapolis police leaders are trading in their white-collared shirts for patrol officers’ blue uniforms in a show of solidarity.

The change went into effect April 30 and comes at a time of heightened public scrutiny of the nation’s police officers, The Star Tribune reported. The criticism has prompted some departments to ditch uniforms that may seem menacing and instead turn to softer looks.

Minneapolis Police Chief Medaria Arradondo decided to reverse the previous chief’s policy meant to make top officers easily identifiable as leadership, said John Elder, a spokesman for the department.
