A new operation similar to "Fast and Furious" was revealed by the LA Times, after the publishing of a series of reports by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), detailing a gun-walking operation called "White Gun ".

the documents specify that the operation began in 2009 at the same time than "Fast and Furious" and both were coordinated by ATF agents.

This new case, indicates that in 2010, the agent.Hope A. MacAllister, involved in "Fast and Furious", traveled to Mexico City seeking access to retrieve evidence of the U.S. weapons that had been siezed by federal authorities in crime scenes. However, the officer was also interested in retrieving guns linked to operation "White Gun" .

Now members of Congress who have spent months scrutinizing the Fast and Furious debacle are seeking to determine whether White Gun was another weapons investigation gone wrong.

"Apparently guns got away again," said one source close to the investigation, led by Rep. Darrell Issa (R-Vista) and Sen. Charles E. Grassley (R-Iowa).

How many ended up in Mexico? Nobody knows, the source said.

Although the ATF records do not specify what it was that the agent MacAllister found in Mexico, it does say that "found weapons in military custody were linked to their research."
Also, the newspaper reported that those involved in "White Gun" were the same that coordinated "Fast and Furious",

The reports also stated that "White Gun" was aimed at the nine leaders of the Sinaloa cartel, including Joaquin "El Chapo" Guzman.

In one of the documents-to which the newspaper had access, MacAllister said according to intelligence reports that the Sinaloa cartel held a training camp in the Sierra de Durango, near the suspected hideout of El Chapo Guzman Loera, and that his criminal group sought to strengthen its arsenal with grenade launchers and .50-caliber machine guns.

To carry out these actions, a member of that cartel identified as Vicente Fernando Guzman Patino, who contacted undercover agents from the ATF with the intent to buy weapons, to whom he said had $ 15 million only to spend in weapons and not worry about money because they wanted the bigger guns and the most extravagant.

In fall 2009, the ATF team sent an undercover agent posing as an arms dealer to Guzman Patino. Photos of weapons, including a Dragon Fire 120-millimeter heavy mortar, were emailed to his "Superman6950" Hotmail account.

According to the ATF documents, Guzman Patino told the undercover agent that "if he would bring them a tank, they would buy it.

After the meeting, an agent and Patino Guzman met again outside a restaurant in Phoenix, where the alleged seller showed the criminal five weapons in the trunk of your vehicle, including a Bushmaster rifle and a Ramo .50 heavy machine gun

The undercover agent said he could get that kind of firepower for the Sinaloans.

Just as Guzman Patino seemed ready to buy, according to the ATF records, the investigation into his activities abruptly ended. The documents do not explain why, and they don't indicate whether he obtained any weapons.

A second case involved cartel members who were seeking shoulder-launched antiaircraft missiles and antitank rockets, according to the ATF records.

The same undercover agent met the pair in February 2010 at a Phoenix warehouse. David Diaz-Sosa and Jorge DeJesus-Casteneda brought 11 pounds of crystal methamphetamine to trade for weapons. The undercover agent showed them shoulder-launched missiles, rocket launchers and grenades before ATF agents moved in and arrested them.

Diaz-Sosa, 26, of Sinaloa, Mexico, pleaded guilty in April to gun and drug charges. DeJesus-Casteneda, 22, also of Sinaloa, pleaded guilty to drug charges. A third suspect, Emilia Palomino-Robles, 42, of Sonora, Mexico, pleaded guilty to delivering drugs as a partial payment for military-grade weaponry.

ATF agent Hope McAllister, a leader in the Operation Fast and Furious disaster, reportedly spent some time in Mexico during the summer of 2010 looking for White Gun weapons among the ordnance seized from cartel killers by the Mexican government. That behavior is not consistent with a tightly-controlled sting operation run by people who know exactly where all the contraband merchandise went. “Sooooo… you guys wouldn’t happen to have seized any of the guns on this list, would you? No? Oh, well, just thought I’d ask amigo, Gracias !”

“How many guns got into Mexico? Who knows?” I’ll bet the answer to that question, at least initially, will not be answered by Eric Holder.

EXTRA NOTES !!!

On December 14, 2010, United States Border Patrol Agent Brian Terry was killed in a gun fight near Rio Rico, Arizona while trying to apprehend a group of armed suspects.Records reveal that agents fired the first shots - with bean bags rounds !!! and the illegal immigrants fired back - not with bean bags - but real bullets from an AK-47 machine gun assault rifle provided by the ATF.
Two weapons found at the crime scene were traced to a Glendale, Arizona gun store that had cooperated with ATF officials in "Fast and Furious."
As of July 2011, the family of Brian Terry is considering filing a wrongful death lawsuit against the United States Government over the operation.

On February 15, 2011, U.S. Immigration and Customs Enforcement agent Jaime Zapata was shot to death by Mexican drug cartel members in northern Mexico. Federal investigators traced the gun used to kill Zapata to a Dallas-area man,[9] but there have still been reports connecting the shooting to the Phoenix-based Operation Fast and Furious. [10]

According to the Los Angeles Times, federal court records and trace
documents from the ATF show that in April 2011, 40 of the weapons from
the operation were found by Mexican police at a home owned by Torres
Marrufo in Ciudad Juárez. Marrufo is thought to be the top enforcer for
the Sinaloa cartel, which U.S. intelligence officials consider to be the
most powerful drug trafficking organization in the world. ( 2ND PICTURE BELOW)

ATF field agents monitoring the U.S.-Mexico border had intended to
apprehend gun smugglers attempting to cross over into Mexico with large
numbers of guns, but were told by their superiors to stand down and let
the smugglers pass.[8]

A gun used by drug cartel criminals to shoot at a Mexican military helicopter, forcing it to land, was found to have been one allowed into Mexico by the ATF.[11]

Two AK-47s sold as part of Operation Fast and Furious and recovered by Mexican police were determined to have been used by members of the Sinaloa cartel in the high-profile kidnapping of attorney Mario González Rodríguez.[12]

In September 2011, the New York Post reported that ATF Special Agent John Dodson had carried out orders to purchase four Draco pistols, which Dodson then resold to known criminals. Dodson had done this under the orders of his supervisor, David Voth.[15]

In October 2011, documents were released that indicated Holder was sent memos in regards to Operation Fast and Furious in 2010, contradicting Holder's sworn testimony before the House Judiciary Committee in which he said he was unaware of Operation Fast and Furious until April 2011. In response, Lamar Smith, the chairman of the Judiciary Committee, sent a letter to President Obama, requesting the appointment of an independent special counsel to investigate whether Holder committed perjury by lying to the committee while under oath.
