Two very popular people have been in the news lately: “Senior government official” and “Law enforcement source.”

When you, the reader or viewer, see or hear either of these mysterious figures cited, proceed with caution. Here are just a few recent examples:

• CNN’s John King and the Associated Press report that the Boston Marathon bombing suspect had been arrested and taken into custody. King based his information on his unnamed “law enforcement source.” The AP never clarified where their false information came from, presumably parroting King or the same “law enforcement source.” They both wound up being wrong.

• NBC, CBS falsely report that Navy chief petty officer Rollie Chance is the suspected gunman in the Washington Navy Yard shooting. NBC continued to name the wrong suspect even after CBS corrected and didn’t retract until sometime after 1pm.

• The New York Times, the New York Daily News, Buzzfeed, and once again CNN and the Associated Press falsely report that the Washington Navy Yard Shooter was armed with an AR-15. All of them cited anonymous “law enforcement sources” while Buzzfeed simply created a listicle claiming “The Navy Yard Shooter Used The Same Style Weapon As Sandy Hook and Aurora.” Buzzfeed never bothered to pull the post, instead opting to change the title to “Officials Now Say That The Navy Yard Shooter Did Not Use The Same Style Weapon As Sandy Hook And Aurora” and at the very end of the post add, “The FBI has stated that they officially have no information about Alexis having an AR-15 in his possession during the attacks, contrary to earlier military reports.” The New York Times later updated their article but haven’t bothered to inform readers that they removed the reference they had earlier with the false report that the gunman was armed with an AR-15.The New York Daily News even ran the false report of the AR-15 on their cover. The AP’s story online still falsely stated at the time of this article being published that the gunman was carrying an AR-15.

• The New York Times became so addicted to the use of anonymous sources in their Syria and New York mayoral race reporting, their own Public Editor called them out on it. She cited one reader’s comment that stated: “As usual, The New York Times is more than glad to help the most powerful leaders in the world get their message out without having to worry about little things about accountability, counterarguments, other facts and various unknowns…”

• The Associated Presss ran this photo which they stated was related to the Navy Yard shooting. They later retracted the photo after learning it was not related to the shooting. (Update: AP now says the photo was redacted because they couldn’t confirm if the photo was related to the shooting, Buzzfeed has details about how the photo has now been confirmed by AP, who plan to potentially release the photo)

Respect and trust must be earned and every mistake should chip away at the credibility of the organization running these reports. However, I wonder if the average reader or viewer actually remembers these mistakes or if they continue to trust again and again. Jon Stewart provided this depressing commentary:

“The lesson they take from this is, it doesn’t matter how much they betray our trust, we’ll keep coming back.”

I wish he was wrong but I suspect he’s right.
