Sally Clark was convicted of the murder of her two sons on the basis of some extremey poor statistics. A doctor claimed that the chance of her two sons dying of SIDS was in excess of 73 million to 1. Very simplistic application of available statistics seemed convincing to jury. At her successful appeal, after 3 years in jail, it emerged that the evidence of the death by natural causes of one of her sons had been witheld.
