A streak of luminous rainbow colors greeted revelers at the 2016 San Francisco gay pride parade, with the celebration tempered by sober reminders of the massacre in an Orlando nightclub that left about 50 people dead and scores wounded.
Gay pride celebrations across the U.S. on Sunday included cities such as New York a Chicago, where a heightened police presence was notable. In San Francisco, hundreds of uniformed officers lined the streets in an effort to safeguard the area from potential threats.
Both uniformed and plain clothed officers were on site to monitor this year's parade as well as other Pride activities throughout the city. Organizers of the parade put in place security measures that included metal detectors at all points of entry and limiting the size of bags brought by attendees.
