Well maybe it is not as ludicrous as it sounds? If Bamber was found not guilty then the whole story that would have told them would have fallen flat and it may have made her look bad. I'm sure the NOTW would have had some clause in place to protect their own interests if the story was not not going to be the scoop that they wanted?
A killer who escaped liability is an even more exciting story.
At any rate you seem to have missed the baot.
The main point is that there is no evidence she made up the claims and told them to police in order ot make money. Evidence of that would undercut the credibility of her claims. Looking for deals before she went to police or evidence she planned to solicit deals and tha tis why she went to police would be a VERY different story. That is evidence the story could have been fabricated for monetary reasons.
A lawyer negotiating a deal well after the claims have been made at worst suggests trying to be opportunistic given the situation not lying to make money. The lawyer has not denied that she went to him trying to find a way to get the press off her back which even hurts the opportunistic claims and makes the lawyer out as the opportunist.
If you had evidence that she wesnt to police so the press woudl want her sotry this would be a very different discussion.
