Cameron Todd Willingham was convicted of deliberately burning down his house in order to murder his three children, and he was executed for the crime. We have asked why Gov. Rick Perry is so afraid ofÂ questions that have been raised about this case. Â As this Nightline report makes clear, the answer is that the fire was an accident, not arson at all, which means Texas executed a man for a crime that was not committed. Worse than that, theÂ proof of thisÂ was presented to the governor before the execution took place, and he ignored it.
