Madeleine McCann Portugal?

I saw some interviews with the Portugal detectives whom where and still are in charge of the investigation and they are just about 100% convinced by the washed away blood the sniffer dogs picked up on the doll in the both of car and apartment that there was sort of incident involving the parents. The British media in retaliation said that Portugals police just couldn't handle a investigation that big and really messed up and needed a scape goat and parents were the only option they were in dublin on rte recently trying to get the investigation more attention and re opened for searches almost desperate looking at this stage, what do most people believe iv gotten some mixed views on this,
