"There is no proof.." blah, blah, blah

Death penalty supporters regularly state that there is "no proof" that an innocent person has been executed and the 122 exonerees are proof that the system "works". Well, I can safely say that in my five years in the anti-death penalty movement I cannot recall a year like 2005 in which there was so much mainstream media focus on possible wrongful executions.

Abolish the Death Penalty has a good post on this issue and considers it a look ahead to 2006.
The innocence argument: A tipping point in 2006?
