CNN loves the story of Lara Logan and Benghazi because, well, Fareed Zakaria, that's why.
Logan is an advocacy journalist. That means she is willing to lie in order to make a story work. She has a stated point of view and a bias that was revealed in her work. She is an advocate for war, for killing people with drones, and for anyone who can help her achieve her goals. Her ethics? Come on. Journalists parted ways with ethics long ago.
