Some years ago, I read an article in a newspaper by a journalist who had sat on a tube train and done nothing whilst a gang of youths had subjected a female passenger to a lengthy bout of sexual abuse.
He wrote about how upset she looked, even when they had got off and she was left on her own again. He then went on about how guilty he felt, but what could he do??
I was upset by it at the time, but then noted in the letters pages for the next few days lots of letters in response, telling him not to be so nesh.
The best one was from some doughty old bird who berated him for not have pulled the emergancy cord and went on to say she had been a regular puller of emergancy cords for over thirty years, in numerous countries and had never once regretted it!
Might I suggest that you contact East Yorkshire buses - [email protected] - tell them what happened, when, on what bus. Ask what guidance is given to drivers in that situation and advice on how you should deal with the matter in the future - ie can you rely on support from the driver.
I note that a forum is to be held regarding Hull bus services on 3rd June 2009. I've moved away from Hull, or else I might have attended this myself. Women's - everyone's safety on buses - should be a priority - it makes economic sense in addition to being a matter of conscience.
If you do manage to send the email, it would be a bit of good coming out of a crap situation.
