More Questions about King George's Authority

John at AmericaBlog asks:

So can Bush assassinate New York Times reporters?

Seriously. I'd like to know what limit, if any, there is to Bush's commander-in-chief powers. Bush said that the New York Times jeopardized national security and the war on terror by publishing its story revealing that he broke the law by spying on Americans. So, can Bush have New York Times reporters arrested and executed for treason? Or at the very least, when the NYT executive editor met with Bush at the White House to discuss whether or not to run the story, could Bush have simply had the NYT editor shot?

I'm serious, I want to know. We've been told that Bush can do anything he wants so long as it's to help the war on terror, so are there any limits?
