It really doesn't matter if you're struggling to take this seriously because key people do. I'm also not sure what exactly you mean be 'evidence', above what I've been reporting. People who are bribed are hardly likely to keep written records of the fact. But how about this: Matt Wrack, head of the FBU, told Prof. Anna Stec (who is reporting to the FBU on cancers in firefighters) that he'd sacked Dave Sibert for "colluding with the flame retardant industry". My mission is far from self-appointed: it's been appointed by many including a government select committee and the contaminants group in the FBU who I'm advisor to.
