"SOME countries are more populous; some have more crime. But in no other country are crime fighters quite so knowledgeable about citizens as in Britain. DNA tests are now so sensitive that they can detect if a person has sneezed or sweated near an object. Jon Swain, a barrister with a background in biochemistry, recently defended a man charged with armed robbery. The defendant's DNA was on the gun that was used, but the defence argued that he might just have been near it after he had been to the gym, and that an errant bead of sweat could account for the presence of his DNA on a weapon he had never handled. He was acquitted." [Sub Required]
