Personally, something just doesn't feel right. There was something about the way this investigation unfolded that made me more uncomfortable and less sure, than relieved as time has gone on. No evidence has been made public and so it's impossible for us to take that into account and so I have only been able to weigh up what I have been privy to - which amounts to details that have constantly changed - which destroys confidence rather than build it in this instance.
Also, for example, unlike the recent Tia Sharpe case where the public were made very aware almost instantly by the press of the grandmother's boyfriend's criminal history - all of which was very serious and conveyed a massive lack of judgement and morals, nothing has yet been made public about MB that would be equal to that kind of history.
There was also 'something' about the way their story was told and about them that made people immediately sense that something odd was going on. Even the police suspected a Shannon Matthews type situation until the body was found up in the loft, after three searches.
Clearly the police are not infallible.
Do I have faith in our justice system? Hard to answer - I'd like to think that all police/ doctors/ MP's etc are moral and honest but having seen first hand various examples of this not being entirely true, it would be naive to not consider all options.
For E.g.
http://www.bbc.co.uk/news/uk-england-birmingham-18901925
Or the footage of the police officer hitting Ian Tomlinson with a baton even though he was walking away and had his back to them, which resulted in his death.
The police in this case hopefully have an abundance of evidence pertaining to the guilt of MB (if he is the guilty party) and will easily convince a jury that he carried out this heinous crime and he will be locked up and the key thrown away.
If, however, it is all circumstantial and he was in the wrong place at the wrong time (visiting his children after parent's evening, driving noticeably because his car wasn't working properly etc) and sort of fits a description or owns a vehicle that maybe in different kinds of light etc could somehow tie him to this crime and is a lad about town who needs to be brought down a peg or two (who knows?) - then for so many reasons, mainly the fact that the real perpetrator is still out there and April could have been found, it would be a complete travesty.
I am not saying he is innocent come what may, I am saying that I am presuming him to be innocent until it can be proved otherwise, which may be instant depending on the evidence brought forth at the trial.
