If we are going to mirror society, how long until we can expect the disabled and ex-offenders with 'unspent' convictions to start applying to join?
That's not really a fair comparison, virtually no large civilian company will want to employ someone with convictions, and certainly not unspent ones. Spent, then yes they'll have to "consider" them by law, but that's no guarantee the person will be viewed very favourably especially when they're up against someone equally qualified with a lack of same "spent convictions".
