Theater-goers experienced mass panic at last evening’s Hamilton show after the audience mistook a medical emergency as an active shooter. According to journalist Joe Khalil, chaos broke out once San Francisco audience members started shouting “Gun!” and running out of the theater.

According to Khalil and the San Francisco Police Department, the actual emergency at hand was a heart attack. Police believe another audience member earnestly thought the person who experienced the heart attack had been shot.
