In 1942, San Francisco City Hall employees began to fear their place of work.  Every day, shortly after noon, employees heard five rapping sounds, seemingly emanating from within the walls. This was followed by a brief pause, then another three raps. Nobody could explain the source of these eerie sounds. 

Tuesday marks the 40th anniversary of the White Night Riots. On May 21, 1979, San Francisco waited for justice following the murders of Mayor George Moscone and Supervisor Harvey Milk at the hands of their colleague, former cop Dan White. When the verdict was handed down, members of the San Francisco Police Department had already begun celebrating White’s minimal manslaughter sentence. However, others demanded answers, protesting in front of City Hall.
