Gay activist Lieutenant Dan Choi was in Russia marching peacefully in a pride parade when he was attacked by the police (see the shocking video). One of the others detained, Louis-Georges Tin, is also a fierce advocate against racism and homophobia. He really caused a stir when he broke into a rendition of "Votre toast, je peux vous le rendre" from Bizet's Carmen. Read more in-depth coverage of the chaotic event here. Incredible how quickly events change for the worst. Read Lt. Dan Choi's complete twitter feed for the last 10 hours after the jump.
