The New York Times reports here in "National Guard Troops Fail to Quell Unrest in Ferguson":
"Early Monday, after a new spate of unrest, Gov. Jay Nixon said he was bringing in the National Guard. Hours later, he said that he was lifting the curfew and that the Guard would have only a limited role, protecting the police command post. ... at the police command post, National Guard members in Army fatigues, some with military police patches on their uniforms, stood ready but never entered the area where protesters were marching. State and local law enforcement authorities oversaw operations there."
