Forgiven (2006)

On the eve of his campaign launch for a seat in the US Senate, a small town District Attorney receives word that the governor has exonerated a death row inmate whom the DA prosecuted five years earlier for the murder of a local police officer. In the wake of the ex-inmate's release and through the prism of the media frenzy, what unfolds is a public vetting of the DA's record. When hard evidence of actual impropriety finds its way into his possession, the exonerated man seeks out the DA for answers.

Unfortunately the movie Forgiven is not yet available on HBO Max.
