Three newly appointed assistant police chiefs in Montgomery County, Maryland, said there will be changes to how policing is carried out, including a shift from what one called a “warrior mentality” to a “guardian mentality.” When the Montgomery County Council voted on the appointments of the assistant chiefs, Montgomery County police Chief Marcus Jones told the council members the three “will be a tremendous asset to our police department.” Two of those appointed are veterans of the department. Assistant Chief Darren Francke served as a captain in the 3rd District, and Assistant Chief Marc Yamada served as a captain in the 4th District.
