A police round-up in West Greenville has the whole town talking. Greenville police headed up "Operation Clean Sweep," which involved 70 officers, resulting in the arrest of more than 40 people Wednesday. Police say many of the suspects are believed to have ties to area gangs. Residents in West Greenville were talking-not about the arrests, but about the difference the arrests have made. Resident Inez Law says she usually stays in at night because she fears for her safety. Law says, however, that Wednesday night she heard something she hasn't heard in a long time-silence.
