It seems that everyone is jumping on the bandwagon - pointing the finger that is.

I've copied this from one of the newspaper reports.

The move comes amid growing anger among those close to the McCanns. They claim police have bungled the inquiry and are now making Madeleine's parents "scapegoats". Today they accused police of failing to fully investigate Mr Murat, the only other formal suspect in the case.
There is a growing belief among the McCanns' friends that police are determined to find the couple guilty at all costs of killing Madeleine.
Close friends of the McCanns remain convinced Mr Murat is still the most likely suspect, although he denies any involvement and the police investigation into him appears to have drawn a blank. Like the McCanns, Mr Murat has been named an arguido - a formal suspect. Sources close to the McCanns insist Mr Murat lied about his whereabouts on 3 May.
Mr O'Brien, Fiona Payne and Rachael Oldfield - all friends of the McCanns - and a Portuguese local have testified they saw Mr Murat helping the search for Madeleine on 3 May.
I cannot believe Murat is no longer being investigated," said a source close to the McCanns, "He is lying about being there on the night. They cannot understand why it hasn't been followed up why Murat lied. Kate and Gerry are being scapegoated.
