Perhaps FF is trying to play HCW at his own game? Claiming to have evidence but not releasing it yet. FF may be trying to put pressure on HCW to release the evidence the prosecutors have?
Very likely and would show some kind of desperation. But maybe he's preparing a war against british tabloids, that keep his client in the media almost day by day.
And to me it looks, as it works. AFAIK PJ starts new investigations, of course due to the huge attention, these tabloids create.
HCW stated, and that is a fact, that there is a possibility too keep someone in custody much longer as the sentence works, due to the danger some repeat offender can mean to the public.
The tabloids, especially the british, seem to dig out every little claim to sexcrimes in Portugal that could be linked to CB, even if they are not proven yet.
But FF is aware, that it can create a picture about his client, that could even have a impact on possible trials in the future.
So maybe his tactic isn't challenging HCW at first, but trying put the mostly british tabloids out of the equation, as much as possible.
We'll see...
