Well, yes, that's obviously the situation and the rationale used in situations such as this by authorities. "You knew you were breaking what the rules were at the time." My questions were not literally questions I had regarding the exact meaning of the TOS. I know what the rules are and I'm not breaking them. I was posing those questions to get people thinking about what happens when rules are created and enforced, but are built on such a weak moral structure that they could change at any time. It makes authority, which serves an important purpose, appear ignorant, arrogant, and weak. Really, I thought it was an appropriate analogy for a discussion about drug prohibition.
Now, this is going way beyond the scope of what we're talking about here, but should we respect punishments given for laws which themselves violated civil liberties? Should we condone the prior hanging of a fellow because, in all fairness, he knew it was wrong to do something that was the privilege of white people?
