In reading the McDonald opinion, I'm astounded by Justice Scalia's concurring dissertation on Justice Stevens' dissent. In his concurrance, Justice Scalia proceeds to very politely tear Justice Stevens a new one.
He very carefully takes apart every one of Justice Stevens' arguments and burns them in the light of logic, precedence and judicial duty. He then spreads the ashes on the grave of Justice Stevens' arguments and waters them down thoroughly.
I love it!
