Fox News reportedly edited out booing and replaced it with applause on an episode of Stossel. Apparently on the show conservative John Bolton dodged a question posed to him. The crowd apparently booed but this was replaced in editing with applause.

This is fairly disgraceful I feel. The goal of a news network is to report the truth. While I know Fox News is an opinion based news network and that's fine. They still, I feel, should not shape public opinion in such a way.
