Just last week a man in Texas was released after 17 years on death row. Even the judge in the case said he it was a travesty. Don't have the guys name but it was an interview on one of the major networks I saw.
Maybe someone else remembers seeing the interview. It was in the last 10 days.
I read an article just this week that they now think a man executed last January in Texas was innocent. I tried to find the article but couldn't. The death penalty is needed but the thing I have against it is the methods. Even lethal injection is now believed to be very painful. The purpose of the death penalty is to stop the worse of the worse from killing. Take his life humanely then society doesn't become what we have destroyed
