This is my concern, I do not remember exactly what I was cautioned and what he wrote on the notes. I was stressed. For sure we talked about it verbally but I don't remember all the questions he wrote down and for what he is prosecuting me. I can only remember a few questions like "are you aware you must hold a valid ticket before traveling" and "do you intend to buy tickets from now on" or similar to that, questions that sound supporting to me. He also said it doesn't worth doing this as I pay for the most part of my trip as I will end up with a fine, however he never mentioned the word prosecute or similar otherwise i would remember.
I'm thinking of sticking to this particular day incident as my reply, I can write a good letter however how can I know if they respond asking about those 2 weeks too ? As per RPI sayings they can only deal with this incident right ? Logic says they can only bring the 2 weeks thing if the inspector wrote down that he asked me relevant questions which I answered yes, problem is I do not remember.
