Catching eve-teasers by policemen in plainclothes was a common practice when we were in college. But plainclothes policewomen will certainly have an edge over their male counterparts in spotting a tease. The move is in the right direction. But we, too, need to gather courage and protest such incidents on the road. I have often seen people in a bus turning a blind eye when they should be raising their voices against harassment of their co-passengers.
