Ferguson Security Forces Use Armored Vehicles To Disperse Protester Crowd In Tense Moments

FERGUSON, Mo.--After more than a week of tension and spurts of unrest, Ferguson security forces moved to break up a crowd of marchers Monday night by driving armored vehicles down the street, blaring a high-pitched siren designed to disperse crowds. No violence appeared to be taking place when the forces moved down the street. Cops refrained from shooting tear canisters and rubber bullets, as they have done several times in the past week.
