That's the police in Istanbul, Turkey, using water cannons, rubber bullets, and tear gas to disperse a gay pride parade that had marched into the central square. No one was exactly sure what pissed off the authorities, but, since it's Ramadan, the festivities probably made some tight-ass, fasting Muslim fundamentalists cranky. The party continued on other blocks, though.
In the United States, you can bet that fuckholes like Mike Huckabee, Bryan Fischer, and Ted Cruz all wished they could hold the hoses at pride parades all over America, blowing the happy right off the celebrating faces.
