Dear John,
I don't know if you've ever watched 'Most Haunted', but they've literally made millions out of broadcasting utter lies and absolute rubbish on TV for years now..... Have a quick look at mainstream, TV at the likes of Colin Fry, John Edwards, Derek Akorah, Mia Dolan and their ilk..... they're all lying through their teeth on a daily basis and making a mint from it too mate.....
All Roll appears to be doing is re-hashing and re-publicising age old, anecdotal stuff and trying to portray it as if no one had ever heard about it before (because of a cover up). It's evidently an attention seeking ploy where Roll sees himself as the hero who is trying to 'bring the truth' to the masses against the oppressive, scientific fraternity.... He's honestly saying nothing new in his 'revelations' regarding life after death. You honestly wouldn't need to 'cover up' the sort of stuff he's talking about - it's been common knowledge for decades, but completely unproven....
Whatever the truth behind life after death and all the mysteries surrounding the paranormal realm - it's certainly not in the grasp of the likes of Roll.....
Cheers John,
Nick
