RFK Jr. was clearly working himself - and the crowd at Live Earth - up.
Screaming treason, as has been common from certain quarters in the immigration debate, is not a small matter. Treason is a capital crime in just about any country in the world.
So, with RFK Jr.'s declaration that people like Michael Crichton should be treated as traitors - probably after some Nuremberg-style trial - for expressing skepticism of the "man-made global warming" claims, he is, in essence, saying that they are worthy of death. And we have had a lot of environmentally-motivated terrorism in this country from groups like the Earth Liberation Front.
I'm starting to get a little nervous.
