I remember a few years ago that the State of Texas executed a man that they knew was innocent, but since he had been convicted and sentenced they executed him anyway.

No such man exists. You are confused.

The American criminal justice system is broken. Since the reinstatement of the death penalty in the 1970s, 123 people have been exonerated from death row in 25 states – roughly one for every eight executed. In fact, the most comprehensive study of capital trials ever conducted found that nearly seven of every 10 death sentences handed down by state courts from 1973 to 1995 were overturned due to "serious, reversible error," including egregiously incompetent defense counsel, suppression of exculpatory evidence, false confessions, racial manipulation of the jury, snitch and accomplice testimony, and faulty jury instructions.

In June of 1993, Kirk Bloodsworth's case became the first capital conviction in the United States to be overturned as a result of DNA testing. Bloodsworth, of Cambridge, Maryland, served almost ten years in prison, including two on death row, for the rape and murder of nine-year-old Dawn Hamilton. After years of fighting for a DNA test, evidence from the crime scene was sent to a lab for testing. Final reports from state and federal labs concluded that Bloodsworth's DNA did not match any of the evidence received for testing. On September 5, 2003, the Maryland State's Attorney announced that a DNA match had been made in the nearly 20-year-old case. Another man has been convicted and sentenced in the murder for which Bloodsworth was wrongfully convicted.

After spending more than 10 years on Illinois' death row, Rolando Cruz and Alejandro Hernandez were finally cleared of a crime that another man had confessed to committing a decade earlier. On November 3, 1995, on the basis of DNA evidence, recanted testimony, and lack of any other substantial evidence against him, a circuit judge acquitted Cruz. Hernandez's case was later dismissed on the same grounds. In his ruling, the judge held that the 10-year legal odyssey of both men defied "common sense."

Above are a few very close cases of innocent men almost being executed. How many were executed that really were innocent? Your guess is as good as mine, but the number is not zero. The justice system in this country or anywhere else is not infallible.

There is more. Go look for it yourself, you lazy bum.
