Two of the year's biggest news stories– the trial of George Zimmerman and the Boston Marathon bombing– were covered in very different ways in the media.

Carol sat down with Steve Malzberg from Newsmax, a conservative media watchdog group and Eric Boehlert, from Media Matters, a liberal media watchdog group to discuss the major media strategies in covering these two stories.

Brian Stelter, CNN's senior media correspondent also joined the conversation to help us quantify how this type of biased coverage can shape our culture.
