Until it is so obvious that they cannot deny it, they will continue to deny anything that does not fit their narrative.
Period.
Justice is built on facts. You and I are satisfied with the facts and the conclusion, but the facts have been revealed very slowly and there are many more left to come.
In order to get past the media spin and false perceptions the case has to be incontrovertible. Anything less will simply be spun as they see fit, which is what they do now with the drips if they do not ignore it.
More like they are more interested in the process and not results. Whats the old saw.
Justice delayed is justice denied.
