Having had personal experience of violence and harassment on trains I really don't think you know what you're talking about...
What this post is effectively saying is "my experience was different to yours, therefore I'm right and you're wrong".
At no point did I say violent crime and harassment don't exist, nor even that they never happen on board trains. I did say that the threat of violence is often exaggerated by the media. There are countless surveys over the last few years that indicate
fear of violent crime is rising among the general population, but crime statistics show a general fall in violent crimes, albeit with the odd spike e.g. knife crime in London.
Back to crimes on board trains, two anecdotes that spring to mind are when a drunkard groped a stewardess on board a Czech train I was on- this occurred in a compartment without doors, the offender fled down the train until he reached the end vestibule behind the loco, and with nowhere to go he hid in the toilet. When the guard followed everyone in the carriage told him exactly where the a$$hole was hiding. He was thrown off at the next stop, but I have my suspicion that the guard also gave him a souvenir in the form of a black eye.
The other anecdote was closer to home, and involved a couple of scallies harassing a young lass who had the temerity to go out dressed in gothic clothing. This time I intervened despite not usually feeling confident enough to do such a thing, and told them that if they didn't stop I'd be sending my (non-existent, but they weren't to know) video of their actions to the Police... I timed this to coincide with a station stop so I had an escape if needed, but in a sense it worked as they turned their attentions to me rather than the girl. It was only verbals in my case and they got off at that stop anyway.
Sorry, I've gone off at a tangent but my point is that I said violence/harassment is not as common as many seem to think- not that it didn't exist at all. If you didn't get that from my previous posts, I don't know what to tell you other than to work on your reading comprehension.
