Keio Electric Railway company is puzzled by passengers' annoying actions such as molestation.
Then, the company decided to set up a security camera inside a train to prevent passengers from annoying.
In Japan, many male passengers are arrested under a false accusation on the suspiction of molestation.
What is worse, some ladies charge male by saying "If you don't want us to reveal your molestation(even when male is innocent), you have to pay for us!".
I hope that the security camera would solve the false accusation.
