There are many core problems that affect this issue. One of which is 'Verifiability not truth' which seems a laudable concept when applied to hearsay, and to allow articles on the paranormal etc. But is often used in BLP articles to justify including untruths, rumours, and to repeat slurs about someone, that happen to have a source that can be verified.

"Truth" is elusive. Many people define Truth to suit themselves. We're not in a position to be judge, defense and jury. So we should not try.
