Check out the article title in the Enquirer shown in this Daily Kos diary:

Muslim Spies in Obama’s CIA
INFESTED: 25 Double Agents Exposed
TORTURE: Why we must not stop waterboarding or close Guantanamo.
PLUGGING LEAKS will DESTORY ISIS!

The guy writing the diary got the manager to come over and ask her why she sells them. As he said, the point was to plant into the other customer’s minds doubts about the titles.

Edit: Just to note, the Enquirer is now working on discrediting the CIA.
