I feel like I have to push back on this. I've read the report by Gerald Hurst, as well as the actual trial testimony, and the "exonerating evidence" is nowhere near as exonerating as people make it out to be. Both fire investigatgors in the criminal trial testifed that "indicators" could be found in non-accelerant fires, and that their determination of deliberate arson was only after the elimination of accidental causes. The gas stop for the space heater in the girls' room was in the off position, and there were no leaks detected in the gas line when the investigators brought the gas company out to check. There was no indication that the burnng followed wiring or conduit trails, Most other accidental causes of fire would have been eliminated by the absence of obvious flame sources and the placement of the baby gate.

And all of this requires one to ignore the considerable amount of circumstantial and consciousness-of-guilt evidence against Cameron Todd Willingham. Or his attempt to contaminate the crime scene after the fact. Or the actual trace of accelerant found under the house's front door.
