Gropers

Today, my friend told me that she was offended by a groper this morning. She lives by herself in Machida, and on her way to Machida station from her apartment a man riding on a bicycle followed her all the way looking at her face laughing in a exetremely close distance. She said she was very scared and run to the woman who was walking a little ahead. These days you can hear about gropers appearing in trains, streets and everywhere everyday. Girls need to be aware of every unfamiliar man when gettin on a train. If you are a highschool girl going to school by train in the center of Tokyo, allmost everyone has been offenden by a groper once or twice. What are ways to deffend us from gropers? Introducing women only cars is a way to protect women, but it isn't a thorough settlement to wipe out gropers. Some times plainclothes policemen are under cover but it is hasn't achieved a big success becase the nomber of policemen under cover is too small. I think that they should take this problem more seriously and increase the nomber of officers under cover. We also need think other ways to wipe out gropers.
