Sgt. Shamar Thomas, the U.S. Marine who confronted New York City police in a now-famous video from the "Occupy Wall Street" protests, appeared on Keith Olbermann's "Countdown" to discuss acts of police brutality against "Occupy" protesters, including Marine Scott Olsen, whose skull was fractured by police in Oakland. Thomas rallied veterans to march together Thursday in a show of solidarity with Olsen and to protect protesters from acts of violence by the New York Police Department.

Keith asks Thomas about right wing allegations that the veterans at rallies are fakes, civilians dressed up in gear they got at surplus stores. "My whole family has served," says Thomas, "I have served. I don't lie about my service."
