Who do you think is stopping them? Are you proposing that Scalia has told them they will be assassinated if they talk to the press about what went on in the meeting? That he has some sort of mind control ray? that he has placed a legally binding gag order on all the press in the US concerning this meeting?
I honestly have no idea what you are insinuating here. How do you think anybody present at that meeting could prevent any of the other participants people from talking about it or prevent the press form reporting on it if they did talk?
If it isn’t then the only people the SCOTUS Justices could talk to would be foreign immigrants and ex-presidents. Is that seriously what you are suggesting? Because everybody else in the entire country is a wannabe president. I wannabe president. You wannabe president. It’s great job. We all want it. Should none of use be able to talk to the SCOTUS Justices?
If you exclude everybody who wants to be president from talking to SCOTUS justices, aren’t they going to get a bit lonely? They won’t even be able to talk to their own families.
Or perhaps you have some clever way of deciding who “really” wants to be president? Or perhaps you will just exclude all the Justices from talking to all politicians, after all it;s a safe bet that every single politician in the country wants to be president, right?
