It's really easy to point out the one mistake every 20 years, but nobody ever mentions all the people murdered by released murderers - in the States, between the years of 1963 and 1997 over 100.000 people would still be alive if they'd executed all their murderers, and the rate soared between 1967 and 77 when the death penalty wasn't used.
Personally I REALLY resent taxpayers' money going to keep these people in comfort at the rate of �2000-�3000 a week, when that money could be used to fight cancer.
Yet the anti-death penalty brigade always claim the moral high ground for some reason.
Its fine if you can't entertain the smallest risk of an innocent person being killed by a wrongful conviction, but if so, then don't ever dare to drive your car again as you have a far greater chance of running over an innocent person and you cannot possibly take that risk can you?
Oh, before anyone questions the figures above, sure I'm quoting them from the web, but even if the figure was 100 and not 100,000 I would still quote them as the principal is the same.
