The Fifth Circuit said this case was primarily about "credibility", but is there anyone, in their right mind, who still finds Osvaldo Aldrete-Davila "credible" (with the possible exception of his own mother)...?? If so, who....?? If Johnny Sutton had to do it over again, do you honestly think that he would still sign that immunity deal with Aldrete-Davila...? No way. OAD has proven that he can't be trusted. And if the prosecutor can't trust him, then that prosecutor has no right to tell a jury to believe him.
Those were issues for appeal, and the appeals court finds no merit in those claims. This is a matter of opinion, but I find it easier to trust the opinion of three highly experienced appeals court judges who had complete access to all the information and briefs.
