i think they would of bought and then grassed him up.
Had the alleged offer really happened then yes the Sun would have bought the pictures. It would have proven their unlikely tale if they had some evidence of the offer. Had the pictures really been offered then buying them would prove that Jeremy had sold them.
Alternatively Fielder could have recorded the conversation and captured on tape irrefutable evidence of Bamber attempting to sell nude pictures of his dead sister but he appears not to have done so. I say "appears not to..." because I find it difficult to believe that the meeting with Bamber wasn't recorded if only in the hope of encouraging loose words from him and having undeniable evidence. However the only evidence presented of this offer having taken place is a story in the Sun on the word of a sleazy hack encouraged by the well known defender of truth and justice, Kelvin Mckenzie

and backed by nothing else.
The motives for the Sun colluding in lies and misinformation on behalf of the police are something we don't even need to speculate on. It is a matter of public record since Leveson as are the criminal charges and sentences given to Sun reporters and police officers partly as a result of Leveson.
This allegation is raised often but funnily enough is never backed up with any evidence which as has been demonstrated would have been simple to acquire had the offer really taken place. The Sun demonstrably disseminated lies and misinformation on behalf of the police at this time on a regular basis and without real evidence (the pictures or a recording of the conversation) it is worthless.
It just shows that some people are prepared to believe any negative story no matter how unlikely. Even those who believe Bamber guilty should question this story. It sounds too good to be true that the alleged killer is attempting to sell nude pictures of his dead sister to the publication, which we now know ran negative stories about those charged on behalf of the police.
If I believed Bamber guilty I would still not believe this story because of it's provenance and what we know of this publication regarding their relationship with the police. It seems incredible that so many are willing to believe as fact something based on a "Sun exclusive"
