They have no choice now; they HAVE to clear their names.
Do you expect them to jump for joy if she backs down and go on with their lives?
Their lives are in ruins and they have to do something to reclaim them and prove their innocence.
It's naive to think they will let this go.
If they are not interested in the money, they could sue just the FA in court, and then force the sorry lot of characters to produce discovery, testify, etc. You get no money but can pinch them good in a very public manner.
Perhaps this has been discussed already, but can they have the arrest/charges removed from their record if found innocent by "findings of fact"? I read about this happening to someone after his case was dropped by a DA. The guy then went before a Superior Court Judge to plead his case.
