Is Furlong completely innocent?  Unfortunately we cannot ever know.  While it is possible to prove someone has done somethin/is guiltyg, it is almost impossible to prove they have not.  In this instance charges were raised but could not be proved.  We then have to assume innocence because there isn't any proof to the opposite.  For all those who want to say "but there was smoke, there must have been fire", I could probably research your life, find a time and place and someone who is willing to make an unfounded accusation against you and according to your rationale that is all that is needed to condemn you.  It may not have happened but there is not a way you could ever prove it.  If you were there at the time it would only be your word that something didn't happen.  Will some guilty people get away, yes but the opposite is to have every innocent person live under a cloud of suspicion.  And yes it could happen to you - especially if you are seen to have any power or money.
