I never said or implied that. Do you have evidence double charging innocent people is train company policy and it being enforced by guards?
My not inconsiderable experience was that in practice guards do not criminalise passengers where there is no apparent deceit and there is a willingness to pay. Indeed even penalty fares are rarely enforced. The guard (and presumably the operator) just want their fare and a not too unhappy customer. That is surely in their business interest. Actually the regular train fare is penalty enough compared to what the passenger could have paid ahead of time.
But, but my fear is that a jobsworth guard (or one that just had a bad experience elsewhere) could help create a criminal record where no criminality is intended and this fear could be what you are playing on. As long as that can be dealt with reasonably by the company or the magistrate then I see no reason to forgo giving criminal records to criminals committing crimes. The latter appears to me the spirit of your campaign and why I cannot support it.
I wasn't trying to misquote you, I was just referring to unmanned stations as 'the example.'
Have a read of some of the posts on the Prosecutions and Disputes page on 'Rail forum', there are a good number of stories demonstrating heavy handed enforcement of the rules.
Generally speaking I think criminal prosecutions are brought too easily in this country. This is of course a separate debate to the issue of sentencing, which can be too light in instances of serious crime.
