In the face of the evidence.

Reading the news, I see that Bradley Murdoch has been found giilty and sentenced to life imprisonment for the murder of backpacker Peter Falconio. Under other circumstances, this story would just be another news story, but one thing about it struck me - the DNA evidence presented was so strong that the chance of someone other than Murdoch being at the scene (and thus being the killer) was 150,000,000,000,000,000 to 1 against.

Under those circumstances, I have to wonder how anyone could present a "not guilty" plea with a perfectly straight face.
