Because it runs just like a video I saw of why you never talk to police without a lawyer.
There are all different kinds of lie. He was pressured into signing a new affidavit that was full of equivocation that was not in the story he told them at the beginning and came after an hour and a half of them pushing him and pushing him to weaken his story. The second affidavit is making the same basic claim as the first one. Claiming he withdrew his affidavit without saying that he signed a new one that ledged essentially the same story after an hour and a half of pressure is a lie of omission.
So here you have ever reliable and honest WAPO saying that he admitted to fabricating the allegations.

Unless there is some other interview where he also retracted this second affidavit this is a huge lie by either the normally reliable "unnamed sources" or WAPO.
