1. And how often do juries get it wrong?

Have innocent inmates ever been executed?

There is no way to tell how many of the almost 1,400 people executed since 1976 may have been innocent. Courts do not generally entertain claims of innocence once the defendant is dead. Defense attorneys move on to other cases where clients' lives can still be saved. (see possible cases of those executed who might have been innocent).

Recently, the case of Cameron Willingham (pictured) has been in the news. He was convicted of murdering his three children by arson in a 1991 house fire. He was executed in 2004. A new report from a national arson expert, prepared for the Texas Forensic Science Commission, has concluded that the original investigation of Willingham's case was seriously flawed and could not support a finding of arson.
