A giant street mural dedicated to George Floyd and the Black Lives Matter movement was unveiled Saturday in front of Floyd’s alma mater, Jack Yates High School. The massive mural, which reads “BLACK LIVES MATTER” and has a painted portrait of Floyd’s old football jersey, spans about two blocks on Alabama Street. “It means a lot for me to come out here and show love and support for my father,” said Floyd’s son at the mural unveiling.
