White Night riots
The White Night riots were violent riots on 21 May1979, caused by an announcement of a perceived lenient sentencing of Dan White for the assassinations of San Francisco Mayor George Moscone and of Harvey Milk, a member of the city's Board of Supervisors, who was among the first openly gay elected official in the United States.
Even the leftist Wikipedia states that the motive for the crime was not anti-gay views but a variety of other reasons.
Regardless, this so outraged the city's gay community that it set off the most violent reaction by gay Americans since the 1969 Stonewall riots. The events caused hundreds of thousands of dollars worth of property damage to City Hall and the surrounding area, as well as injuries to police officers and rioters.
Several hours after the riot had been broken up, police made a raid on a gay bar in San Francisco's Castro District. Many patrons were beaten by police in riot gear. Two dozen arrests were made during the course of the raid, and several people later sued the SFPD.
In the following days, gay leaders refused to apologize for the events of that night.
Later, the Jewish Dianne Feinstein was elected Mayer and appointed a pro-gay Chief of Police. Leftist Wikipedia claims that this was due to the violent riots, despite that the violent riots may have increased anti-gay sentiments and despite that Wikipedia also stating that LGBT influence was increasing already before the riots, with up to a quarter of San Francisco reported to be gay at the time.
