But then again
I just read Tom's post tracking down the true origin of that quote. You're right not to believe your first impression, and Tom just demonstrated how we should be careful of a second impression too.
Your post illustrates the fundemental problem when people start playing fast and loose with the truth. We lose social cohesiveness when we don't know who to trust. And it illustrates why a government should resist with all its willpower the tempation to take the easy way out and keep more secrets than absolutely necessary. Transparency is difficult in the short term and sometimes it's a risk, but in the long run it always pays off.
