It never ceases to amaze me how seemingly intelligent people still fail to recognise this situation.
It is true that the Report suggests reasons why the McCanns were not involved in Madeline's disappearance but that is as far as it goes. The crime is unknown, Madeline's fate is unknown and the perpetrator(s) if there are any is unknown. The McCanns were made arguidos in the concealment of Madeleine's body and the simulation of an abduction. Since proof of these offences failed to materialise the prosecutors were forced to remove the arguido status and write the Report.
In the eyes of the Law the McCanns are innocent until proven guilty. The legal question of them being 'cleared' therefore does not arise. The Press use the term 'cleared' as an emotive throw away label because it sells newspapers, it has no real relevance to the McCanns. The truth is the McCanns have never been cleared of involvement in their daughters disappearance and if evidence were found tomorrow which pointed to them having been involved they can be arrested just like anyone else.
Until such times as someone is convicted of Madeleine's abduction or it has been determined that she died following some misadventure then there will always be suspicions surrounding the parents. That I'm afraid is real life.
