This stunt that This Morning pulled is a classic example of the hysteria and poisonous atmosphere generated by a witch-hunt. Schofield was plainly trying to embarass the PM, and it was a thoroughly stupid stunt, passing off internet circulated gossip and rumour as some sort of research. It clouds and confuses proper investigations and inquiry, it further fuels the hysteria, it can permanently ruin individuals lives to no end whatsoever.
He should not be sacked, but he should be reprimanded. And for those supporting this media led sensationalist revelatory hype as useful - just remember what happened to Mr. Chris Jeffries.
If the Schofields of this world have any serious evidence, they should present it to the police, not spring it on a politician, on air, in an effort to grab airtime, headlines and ratings.
