SFist brought you this news yesterday, but somewhere around "100 police officers, Muni inspectors and sheriff's officials were involved in Citywide Operation Safe Muni," conducted between 1 p.m. and 8:30 p.m. on Wednesday. CBS 5 reports that citations were issued for fare evasion, not having a pass or transfer, and eating/drinking on public transit.
According to Sgt. Lyn Tomioka, "Six people were arrested on felony warrants and three others were arrested before being cited and released."
This sweep was the first of its kind in San Francisco. This comes on the heels of this year's study that concluded one out of every 10 passengers doesn't pay their fair share.
