Several U.S. service men and women, many of them veterans, marched from the Denver Colisseum towards the Pepsi Center Wednesday Aug. 27, 2008. Thousands of anti-war demonstrators converged near security gates outside the Democratic National Convention hall on Wednesday, chanting slogans and asking to talk to party officials about getting U.S. troops out of Iraq. Police in riot gear ordered the group to disperse, and after about 15 minutes many protesters drifted off.
