Like most statistics of that nature, it's essentially a 'population study'. That means it's looking at the evidence of all cases where someone was convicted, put in prison, then released later on due to new evidence coming to light that proves they didn't do it.Baresark said:Haha, I can't help but question that statistic. I mean, they would have to know for sure that innocent people are in jail. And if they know they are innocent, they shouldn't be there.CrystalShadow said:It's a pity false conviction statistics suggest about 5-10% of all people in prison are innocent of any crime...Baresark said:John Locke said a similar thing. It's better that ten guilty men go free than one innocent man goes to jail.FlashHero said:I agree with this court ruling. Would we rather have 100 fair-free people and 400 hoodlums pirating stuff out of jail...or would we want 500 people in jail no matter what they did or did not do?
America has the largest prison population in the world. That same percentage means there are between 360k and 720k people in jail here, that are innocent.
Now, inferring things from something like that is always a bit uncertain.
So, no, it doesn't say we know who is in prison that's innocent. (Or that this is guaranteed to be a valid generalisation of the cases it's based on.)
But even so, that's what the evidence of cases that were overturned suggest.
What's worst about it is that the statistics for wrongful convictions is highest with murder cases that involve the death penalty.
