Indeed the CPS and police investigating the matter know far more of the specifics than we do, but I personally wouldn't put trust them to apply reason and common sense any further than I could throw 'em.
They do make some really daft decisions sometimes, most if not all of us can think of specific cases which highlight the level of hypocracy that exist within the confines of our criminal justice system.
The cynic in me says the CPS would pursue a case such as this even if only just to make an example of an innocent couple for the purposes of demonstrating to < insert name of desired non-christian religious group whom the CPS wishes to show equality> that both the police and CPS enforce UK law without bias nor prejudice. The optimist in me says "Aye that could be true, but that might not be the case here.".
