David Shaw is at least as reliable as Wikipedia and probably a lot more reliable than this. However, I accept your point about his book, Nick. The problem with Shaw is that we don't know what the source of his information is. yet isn't this true of all of the WHF murders authors? All we have are their claims to have interviewed various persons involved, extended family, EP officers and so on. What tends to happen in practice is that antis tend to accept the views of Colin Caffell and of those authors who extensively interviewed Jeremy's extended family, whereas pros tend to accept the views of those who claim to have extensively interviewed police officers.
Choc, I have only used Wiki as a point of reference to others for information, or to discuss the uncorroborated statements they have made! - and stating that David Shaw (DS) is probably a lot more reliable than Wiki is very subjective.
Wiki's narrative is very brief, whereas the "novel" produced by DS could contain far more misleading statements than Wiki.
I have also not built Wiki statements into my posts in order to support them, as you have done with David Shaw's uncorroborated account of the sniffer dog.
It's difficult enough to believe the official EP documents presented on the forum, never mind the various books. I have read Roger Wilkes and found that reasonably non bias.
