McGrath - the first reference to the Whitechapel Murders was made by guest - in a rather sweeping statement, suggesting that there was proof as to whom the murderer was. I placed the link to the casebook site, suggesting that it was a place for lengthy, intelligent discussion on the subject. I made an error in doing the link and so re-posted it correctly, however, it also struck me that the first comment was from somebody who was clearly not very well informed on the subject, but was interested in it and could, perhaps, therefore be described as an 'enthusiast'. Not the perfect choice of words, perhaps, but not a million miles away from a basically appropriate way to describe someone who has several books on any given subject on their shelves (or has borrowed said books from a library or a friend). As the original Guest said that 'many case studies have proved this', it would suggest they have done quite a bit of reading on the subject - of what, exactly, to have come to this conclusion, I am not sure, but that isn't the point.
