This story is literally unbelievable. A man accused of setting his own house on fire and killing his three young daughters back in 1991 was convicted with ridiculous and unreliable evidence and executed in 2004. Sadly, expert criticism of incorrect assumptions based more on wives' tales than facts was not enough to get a Texas justice system to reconsider one man's fate.
The interest here is all in the story. Watch politicians and activists alike take advantage of this case to push their own agendas and cover their own mistakes. While the case brought about motivation for challenging and changing the system, it was too late for Todd Willingham.
I would comment that this story, which hits so close to home, at first seems fairly biased, but it becomes evident that the facts are simply ugly and embarrassing. Fortunately, a UT teacher and a UT Law graduate are knowledgeable about this case and the Texas law as well as seasoned in film, so we get a clear look at what happened and what is still happening. We only have to hope that an unveiling documentary like this will help serve to prevent such injustices in the future.
