When anti-war Iraq veteran Reverend Lennox Yearwood, President of the Hip Hop Caucus, tried to enter the Petraeus hearings wearing an "I Love the People of Iraq" button he was refused entry. When he questioned why others behind him in line were being allowed in while he was not, police threatened to arrest him and ultimately jumped him and tore some of the ligaments in his leg.
Luckily, someone had a video camera and captured the whole incident. And now BoingBoing has posted it, too. This should be interesting to watch how the story unfolds.
UPDATE: Reverend Yearwood YouTube's his side of the story here, and addresses the ANSWER Coalition here.
