One thing which intrigues me about this is the blackening of the characters of the accused in order to support the accusation. In all the miscarriage of justice cases I've looked at, this has been a constant theme. The accused is said to have been a bad person in this or that way, thus his or her guilt is certain. Sometimes these tangential accusations are true, sometimes not, or much exaggerated.
Look at this one.
http://www.justiceforsionjenkins.org.uk/ Jenkins was ludicrously accused of murdering his stepdaugter for no known motive, in the space of about three minutes, within earshot of two of his other children. To support this the prosecution pointed out that he had - exaggerated his educational qualifications in his application for his teaching job several years earlier.
This photo of Barry George, featuring George with a non-functioning replica handgun, was used to paint him as a desperate, terrorist figure. It's quite clearly a photo of an inadequate with a gun fetish playing dress-up. But it got him convicted.

It happens time and time again. It shouldn't matter if the suspect has been known to eat babies. If there is no evidence connecting him or her with the ACTUAL CRIME, there should be no conviction. This is one of the worst examples I've come across, but it fits the pattern horribly well.
