Media Matters gives a great take on how news outlets can misinform viewers/readers with partial comments.
Take Sen. Harry Reid and the quote going around in which he was asked if he would fund cancer research for children during the government shutdown. The answer being reported is, "Why would I do that?"
But Reid's answer was in repsonse to Sen. Chuck Schumer who was himself responding to a question about the shutdown from CNN's Dana Bash.
Reid had said he did not believe Congress should pick and choose what to fund, prompting Bash to ask, "If you can help one child who has cancer, why wouldn't you do it?"
Sen. Charles Schumer responded to her question by asking, "Why
pit one against the other?" and Reid added in, "why would we want to do
that? I have 1,100 people at Nellis Air Force base that are sitting
home. They have a few problems of their own."
For CBS News and others to report it in the way that they did is misinforming and bad journalism.
