I think combinations and layers of problems and zero willingness to acknowledge and investigate. Itâ(TM)s perfectly feasible that *some* of the postmasters were unprofessional but there was little support because they relied on legal threats being the leverage. Throw in some race conditions that probably got fixed over time but never acknowledged etc. also the courts themselves didnâ(TM)t help because they didnâ(TM)t push back when it was obvious the prosecution had nothing. Judges can throw out cases but they let them be heard.
