Barack Obama has apparently ordered the assassination of a U.S. citizen without a trial in the name of fighting terrorism. This is an even more blatant assault on the Constitution than anything the Bush administration ever did. Bush merely spied on, tortured, and imprisoned American citizens without a trial. He never actually had one killed.
I predict that the people who are calling on members of the Bush administration to be prosecuted for war crimes will not be calling for Barack Obama to be prosecuted for conspiracy to commit murder, even though that is clearly what this is.
