Right from the start things were bad: the crime scene was trampled by curious MPs, the forensic work was abysmal, one of the first responding MPs saw a woman with a floppy hat, later McDonald mentioned a woman with a floppy hat. The Judge clearly did not allow a fair trial. Later police work was absurdly botched too. I've always felt that the trio may have been encouraged to select that particular victim. It was not some random crime.
