Milton-based activist group “If Not Us, Then Who?” drew together hundreds of protesters, most wearing masks, for a Black Lives Matter rally in front of City Hall on Sunday afternoon. Chants of “If not us, then who? If not now, then when?” and “No justice, no peace” filled the air. Activist Gene Stilp joined the crowd, burning a conjoined Confederate and Nazi flag as well as a Trump flag conjoined with the flag of the former Soviet Union in a trash can amid cheers and applause. Informational booths for the NAACP and to help protesters register to vote were on site. The rally went mobile for a brief march through the city before returning to City Hall. West Street, between City Hall and the Williamsport Water Authority, was closed for the duration of the rally.
