Did Texas execute a wrongly convicted man?

Cameron Todd Willingham was convicted of setting his house on fire in 1991 and murdering his three young daughters in Texas, and subsequently executed ten years ago. The execution came despite pleas from family members and death penalty opponents that Willingham was innocent. But now newly discovered evidence shows that Willingham may not, in fact, have started the fire. RT's Ameera David talks to Bryce Benjet, staff attorney for the Innocence Project, about what went wrong in the case that Texas may have executed an innocent man.
