Oh come on, you keep up with the news as well as anyone else. Don't tell me you have not happened across a news story about someone being released from death row after having been found innocent.
I asked you to name someone innocent who has been executed, not someone released from death row. It isn't my burden to research and disprove your argument.
The releases don't always prove innocence. It could be there just isn't enough evidence after 15 years to convict and the charges are dropped.
