Why is it wrong? Did he break the law? If he didn't, then your entire argument about how he ought only respect the law falls apart. If he broke no law, no foul was committed, if I follow your logic correctly.
The Declaration, I must remind you, is a little more than a pretty piece of paper. Our founders thought enough of it to refer to it quite a bit, as has the Supreme Court, in over 400 cases! You say it isn't law, but I argue that it is, because it is only by its reasoning that we claim to have a right to make any law, independent from Britain, on our own.
