Well, Jack the lad has a point in a way, people who are really guilty do get aquitted on a regular basis (the man with the shotgun, Flying Lawyer???)
However from expereince, those that are guilty and manage to get off on a technicality, such as the CPS changing the charge to the wrong one, or because a piece of paper is wrongly writen, usualy come again.........
In this case, unless somethings changed, its still not clear if he's been chaged and bailed to appear at court, or if he's been bailed to return to Heathrow nick...It makes little difference I suppose, excpt if he's been bailed to appear in Court, then all the elements needed to prove the offence are there.....
