The rainbow flag has been a popular symbol of gay rights since the late 1970s and has been used in various forms at gay pride events for years. Police are calling the disturbance an isolated incident and say it does not pose a threat to other events. Parade organizers Capital Pride decided to cut the parade short after the scare, but say that after consulting with police the rest of the events scheduled for the weekend will go on as planned. Gay pride is celebrated around the world in June, with some parades set on or around June 28 to mark the anniversary of a 1969 police raid at the Stonewall Inn gay bar in New York, where patrons fought back and inspired the modern LGBT rights movement.
