In Revenge of the Sith there is a scene where Obi Wan and Yoda look at the security recordings (@1:25:30 of film) of the younglings assassination at the hands of Anakin/Darth Vader and then how Vader kneels before Palpatine. Why don't they catch that video and put them in the hands of the press?
Sure the supreme Chancellor may control some of the press in the galaxy but couldn't this move have helped people know what kind of person Palpatine is? Doesn't ordering the death of hundreds of children put Palpatine in a delicate situation?
