The two stories in the links below are very recent, and they are not uncommon. The criminal justice system is not perfect; mistakes happen, and innocent people are convicted of murder. Luckily, David Robinson and John Bunn were not sentenced to death. They “only” lost 17 or 18 years of their lives. Once someone is executed, efforts to prove his innocence usually stop. Remember Cameron Todd Willingham? Troy Davis? How many more innocent people have to die before the death penalty is abolished?
