As Troy Davis faces his fourth execution date, the effort to save him has come to rival the most celebrated death row campaigns in recent history.
On Monday, the Georgia State Board of Pardons and Paroles will give Mr. Davis what is by all accounts his last chance to avoid death by lethal injection, scheduled for Wednesday.
Whether history will ultimately judge Mr. Davis guilty or innocent, cultural and legal observers will be left to examine why Mr. Davis, convicted of killing a Savannah police officer, Mark MacPhail, 22 years ago, has been catapulted to the forefront of the national conversation when most of the 3,251 other people on death row in the United States have not.
