Demonstrators from the Mass. Action Against Police Brutality rally march along Seaver Street in Boston on Tuesday night. (Robin Lubbock/WBUR) Several hundred people gathered in Franklin Park to mark the anniversary of the killing of George Floyd — and to call for local officials to do more to combat police brutality. Since Floyd's death last year, his killer, former Minneapolis police officer Derek Chauvin, was found guilty of murder. Across the country, government officials, businesses and schools have promised reforms to fight racism, increase equity and hold perpetrators of racial violence accountable. Locally, that's meant a host of police reforms, including a new statewide commission to oversee policing. Boston now has an office charged with investigating police misconduct.
