Did a bit more research...
Ye gods. ATF brass, DOJ and White House intimidation of whistle blowers, reporters and agents. The Aug 15 2011 bribe to Mexico of $500m, laundered through Merida Initiative, if Mexico STFU. Hell, the transcripts of Acting Director Melson testifying before Congress alone are downright disturbing. Apparently ATF agents were supposed to take the fall for the DOJ, according to Melson who has since been reassigned to the DOJ.
according to July 26 2011 Oversight Committee testimony by ATF Attaches to Mexico, they were specifically ordered not to inform the Mexican government and keep MX officials in the dark. It was not a failure to notify re F&F, it was intentional. According to the personnel who implemented it, Agents Darren Gil and Carlos Canino. There is an difference between failure to notify, and intentionally smuggling weapons into a foreign country while intentionally making false statements to said foreign government.
Holder likely committed perjury re when he was notified about F&F, and possibly who authorized what. Napolitano also likely committed perjury regarding other agencies involvement in F&F. That is why Obama clamped down on them at Holder's request, and bloody quickly. Minimum of two cabinet members would face perjury charges, and gods alone know what other lawsuits and criminal charges. In addition, the DOJ IG has a report ready to lay the blame solely on the BATFE, and call it a rogue operation strictly by BATFE personnel. This is to intentionally ignore DOJ, Border Customs, Immigration, DEA, FBI, etc were part of the task force involved...
It physically pains me to say this... but... a lot low level ATF agents are the heroes here. They expressed their doubts, leaked information to the proper authority to defy the DOJ gag orders, risked their careers and their lives. Several have also been crucified by testifying before Congress in defiance of the DOJ gag order.
The other heroes are gun dealers and gun bloggers. The gun dealers for thankfully retaining evidence that the BATFE used coercion to force them to make illegal transactions, and the gun bloggers for actually getting the word out.
The "good" news is, worst case. The documents are blocked, the Congressional investigation is shut down by sympathetic Republicans, and the coverup is more or less successful. The BATFE is going to slapped down hard. They are the official fall guy if the DOJ successfully manages to block the release of those documents. If Obama wins a second term, he will not be touching gun control with a ten foot pole, because it would restart investigation into the DOJ's role in F&F.
The best case is DOJ officials are sent to prison for numerous crimes, including accessory to several hundred murders, violating international arms trafficking laws, perjury, obstruction of justice, etc. BATFE is also sharply restricted.
If this actually came out in the news, it'd make Watergate look like a picnic.
