This major revival of Emily Mann’s documentary drama is about the trial of Dan White for the murders of San Francisco Mayor George Moscone and gay Supervisor Harvey Milk, and the violent reaction that followed. For GLBT men and women of a certain age, Execution of Justice is sure to stir sorrows and angers long forgotten. For younger GLBTs, it’s time to learn—if you do not know—about a defining moment in post-World War II GLBT history. Stonewall and the Dan White Trial: Nothing has been the same for any of us since. Nothing. Gary Griffin directs a potent cast for About Face Theatre. Execution of Justice runs through Feb. 18 at Victory Gardens Greenhouse; 773-871-3000; $20-$45. Pic by Michael Brosilow
