The Daily Caller's Blatantly False Fast And Furious Story
The Daily Caller's Matthew Boyle is reporting  that a Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) memorandum in the possession of congressional investigators "described a specific operation in which guns were allowed to walk across the Mexican border" during Operation Fast and Furious. The memo was drafted and, according to Sen. Chuck Grassley (R-IA), "forwarded to DOJ headquarters" the day before the Justice Department told Congress that no such gunwalking had occurred. Boyle suggests that this indicates that DOJ knew gunwalking had occurred in Fast and Furious when they issued their statement to Congress, and thus that they "may have tried to cover up" the use of such activities. This assertion is false and is directly contradicted by the memo in question, which does not detail a gunwalking operation.
Instead the memo  describes a case where ATF agents were forced to "leave the immediate area" of the stakeout of a suspected gun trafficker to avoid detection. While repositioning, the suspect left the area and eluded capture. From the memo:
Special Agent [Gary] Styers was asked to describe the operations and relayed that one of the operations was a suspected transaction that was to occur at a gas station and detailed agents were asked to cover the transaction. While positioning to observe the suspects, Special Agent Styers and other detailed agents were told by Special Agent [Hope] McAllister that the agents were too close and would burn the operation. Special Agent McAllister told all of the agents to leave the immediate area. While the agents were repositioning, the transaction between the suspects took place and the vehicle took possession of the firearms and eventually left the area without the agents following it.
What was described was an unsuccessful law enforcement operation, not ATF acquiescence to the illegal transfer of firearms. Boyle includes much of the text of that passage in his article, but nonetheless concludes that Styers was describing an operation "in which guns were allowed to walk across the Mexican border." Boyle also neglects to mention that Styers, the author of the memo, wrote that during his involvement in Fast and Furious "he did not see any firearms cross the border into Mexico."
This isn't the first time that Boyle has made false claims in his reporting that are easily contradicted by the very documents he cites. In September 2011, Boyle published an article  claiming that the Environmental Protection Agency (EPA) was attempting to hire 230,000 new workers at a cost of $21 billion per year. The legal documents cited by Boyle actually indicated that this was a scenario the EPA wanted to -- and eventually did  -- avoid.
