"Does this news report verify its statements? (Does the reporter, in other words, open the freezer?) Has this person or organization created a report free of entanglements or agendas? Does the editor or producer stand by the accuracy of the report and hold accountable whatever sources are quoted?" --Renée Loth "What's Black and White and Retweeted All Over? Teaching News Literacy in the Digital Age."
