What a load of cobblers! I chat to him every other day and no, it is not on a pay phone in a prison.
I think you will find there are a lot of bitter people who have nothing better to do that slate/rubbish their opposition. I am learning this already, getting threats of legal action for having an opinion on forums and threats of sending the police around because I work on sub 12ftlbs airguns, which is perfectly legal. The police know what I do, how I do it and are perfectly happy I am not breaking the law.
If anybody has any "proof" of him being inside then feel free to get in touch.
