Bobby : Freddy Rodriguez would have been shot

the POTUS brother has just been shot by a brown man

then he is approached by Freddy Rodriguez who is wearing a waiter outfit

assassins don't wear a sign that says ASSASSiN they wear a disguise a uniform

Kennedy's bodyguards would assume he was.. you know

You don't know much about Kennedy's bodyguards, do you?

Oh, and Bobby Kennedy wasn't Lyndon Johnson's brother. Care to try for strike 3?

You're right that Bobby Kennedy wasn't LBJ's brother, but he was, in fact, the brother of a president I think we all knew what the OP meant by referring to him as the POTUS' brother
