@ redken 'executing too many innocents' -- innocent of what as plenty of question marks around quite a few after a quick check ? :-?

'unlawful killings 300 in 1964'
'The number of killings recorded by police rose to 636 in the 12 months to March 2011'

btw you mention Downing and although released due to lack of plod correct procedure at the time[well done :P ] after over 25 years and now the case is closed. I understand he remains the prime suspect but cannot be retried and refused to be interviewed again even though there are allegations that he has confessed to the killing.

Ken - a dead murderer won't re-offend=fact!!!

'29 people released after being convicted of murder and six people convicted of manslaughter, killed again between 2000/1 and 2010/11'

It won't be re-introduced so we will all continue to keep the increasing number of killers alive and well
