re: Sect 1042
I don't have access to my previous posts on this, and don't want to reconstruct them, but I pointed out a while back that most of these regulations go back far past Bush, or even the previous presidents. Much of the Insurrection Act dates back to 1807.
What a lot of conspiracy nuts are trying to sell is that none of this existed until recently.
Wikipedia has a pretty good side-by-side comparison of recent changes.
