Double jeopardy ensures defendants are not brought to trial on weak grounds  The implications of this should be looked at carefully. This would grant police and the prosecution the right to prosecute an individual if the evidence against them can be ‘reanalysed.’ Surely almost all cases could see such ‘improvement in investigatory techniques,’ allowing the state to pursue individuals at will. Presumably this ‘generation’ of techniques isn’t the last; why won’t the same logic hold in asking for a third trial? A fourth? A fifth?…Subsequently, if the ‘double jeopardy’ rule is scrapped, police work will be sloppier, because police detectives will know that the insurance of a second trial exists. The ‘one-shot’ rule forces investigations and prosecutions to be of as high a quality as possible. The abolishment of double jeopardy would be ‘merely a shortcut to prosecutors seeking unlimited re-trials until they get the verdict they want’ 1. Courts cannot be permitted to be tied up in such cases, nor can prosecutors be allowed to destroy the lives of defendants by enforcing such constant emotional turmoil.  1. Bosscher, M.
