An accusation doesn't imply you need the evidence, that's up to the authorities to find out and apply the proper sentence for the one who committed the "crime". And clearly, the "authorities" here don't have the proper tools to discover what happened.
@Sister Sledge , nobody is blaming a specific person, I don't know what you are talking about. And as you said, it is easier to blame the enemy tribe, if it were the opposite it would be the same, you know it. Nobody can blame INQ member for accusing/suspecting Nomads, it's human nature and their right to be upset.
This discussion is a dead end without any mediator, therefore, I'm leaving it.
