"The women only in the car" is a good idea.

Today, I listend to presentations. The second presentation is very interesting to me. I agree with the idea to need the women only in the car because there are many sexual crimes in the subway and subway station. In subway, there are several alternatives to prevent these crimes.
First, the police or guards must patrol. As you know, you may have seen on the news. Intentionally, criminals touch women's body and they take pictures of the underwear which women wear. To make money, they sell the photos on the internet. To prevent these crimes guards must patrol. However, In my experience, I often take a subway to go to school but in rushour, I have been misunderstood. On the other hand, I think most of women seem to be too sensitive.
Second, CCTV have to be installed. By monitoring, crimes can be reduced but it requires a lot of budget. So the company should install  real cctv and counterfeit cctv. The company can save time and money.
Third, the women always have to carry thing for self-defense such as gasgun, whistle and stun gun. Sexual criminals are surprised and embarrassed. I think it is best to defend their own body.
Forth, why don't you put on mirrors on the ceiling of subway or put on posters of sexual crimes on the wall? I think these are good ideas.

these solutions, sexual crimes are able to be reduced. In addtion, I think 'the women only in the car' will contribute to reduce sexual crimes.
