>> Thief is a thief ... unless they are a Lord.

So he wasnt a thief. The laws of the time ebbed and flowed based on the social standing of the alleged perpetrators. That was the then accepted rule. It is less true today but not absolutely. Who are we to ignore the actions of a past select committee? Are we to revisit every not-guilty decisison on the basis that a modern investigation would have acted differently? By way of example, women were in the past treated very badly. Revisiting every historic legal determination that stripped a woman of her propery would render all modern property rights suspect.
