Innocent men being executed:
The political Left has been trying for decades to find examples of innocent men who were legally executed. And certainly, it happened a long, long time ago, but in modern history, not so much. There are innocent men who have been picked off Death Row, and convicted men who have been released due to faulty evidence collection (not determinative of whether they actually committed the crime), but examples of men who were actually executed, and were proven to have been innocent...I don't think there have been any. There have also been men under L-WOP sentences who confessed to other murders for which other have been convicted, but...consider the source.
I can't make a categorical statement, but I have never heard of anyone since, say 1930, who has been conclusively proven to be factually innocent, and was executed by the State. And again, Lefties would LOVE to find such an example, in order to bolster their case for the elimination of capital punishment. But they can't, without fudging.
