this picture means NOTHING.
Scalia, Thomas, Roberts and Alito have not been given any orders.
The picture is notable in that the meeting was requested by Obama and Bush never met with the justices upon him upon his elections.
Ah, you are so wrong.
The picture means everything.
Their Orders were the US Constitution and
the Canons of Judicial conduct, which demand there be
no appearance of impropriety, and a natural born
citizen in the White House..
They met with the litigant before their deepsixing
the Pet. Cert. and the Constitution they swore
(and lied) to uphold.
