The statements I have read from Sotomayor display a subjective and not very intelligent perspective. It doesn't take a lawyer to see that pretty clearly. It seems she is lofted way above her highest level of incompetency. Roberts, of course, is merely Epsteined and doesn't rule from law, he takes dictation and wraps it in a legalese package for his owners.
It seems from those overheard tirades, Roberts is not above threatening and intimidating his fellow justices. He's also muscle for his owners.
