If I post an anonymous picture that I find on the internet, can you identify that person by name and address, of course you can't but you seem to have this unshaken belief that CEL can.
You say they have the driver's picture, name and address, NO they don't, they have a picture that could be anybody in the world and the Registered keepers name and address, now whether the registered keeper and the driver are the same person at the time of this incident that is a problem for CEL, that is why your were advised to even avoid hinting at it.
Also, stop going on about the disability aspect, CEL are not listening to you and are certainly not interested in any point you are trying to make regarding it. You were advised to put the disability aspect to one side for now, as at the moment the matter is contractual, the disability part may, or may not be relevant when the time comes and you will be given advice regarding that by the guys on the forum.
Don't try and play one advisor against another, take all the advice as a whole, if you are not sure or think you are getting conflicting advice ask for clarification.
I appreciate it is not your ticket and you are trying to help out a third party, but it is frustrating when posters are repeating advice and you seem to go your own way,
