Johnny Webb/John H Jackson (Cameron Todd Willingham new evidence)
Frontline has run an interesting video about the Todd Willingham case (man executed in 2004 for arson/murder). The Innocence project has filed a grievance based on the recated testimony of a prosecution witness and allegations of misconduct by the prosecutor.

The video has interview clips of both the jailhouse informant now recanting (Johnny Webb) and earlier footage of the prosecutor now under scrutiny (John Jackson).
The whole clip explaining the current situation is about 7 and a half minutes. Timestamps to the interview clips are:
0:32-0:41 Prosecutor Jackson in 2010 (about Willingham confessing to Webb)
2:10-3:03 Two interview clips: Webb in 2010 saying Willingham confessed, now saying it never happened
3:43-4:11 Jackson in 2010 denying any offers or deals being made
4:15-4:33 and 5:44-5:55 Webb about the deal
