I also was rather astounded at that statement, especially when it comes from a Supreme Court Justice. How can one know what the Framers of the Constitution intended without reading what was written by the Framers, understanding the writings influencing the minds of the Framers, and subsequent rulings from the early days of the Republic?
There is a distinct disconnect in Breyer's statement.
I'm also surprised that Breyer would admit that he does not believe in the rule of law.
