'We Canât Stop Now': Boston Protesters March For Racial Justice In The Wake Of Chauvin Verdict Protester Sierra Wilcox, 31, from the South Shore, demonstrates at a march against police brutality outside the Boston Police Headquarters in Roxbury on April 21, 2021. Tori Bedford / GBH News As rain clouds threatened to break and thunder rumbled in the distance, Monica Cannon-Grant, a local activist and founder of social justice nonprofit Violence in Boston, vowed to stick it out. âWe're going to be out here regardless,â she said as a crowd began to form Wednesday outside a nearby Boston Police District station. âBlack folks are dying in the rain, the snow, the sunshine, on a Sunday, it doesn't matter. So we have an obligation to show up not just for the Floyd family, but for the people in the city of Boston who get killed on a regular basis.â
