You make it seem like they are getting away with something. They in fact are only delaying the inevitable. In the normal course of things this is going to take awhile to litigate in civil court to get the docs and then the indict in criminal court for any criminal actions.
The criminal component will take place after a new POTUS and new US AG are installed in January. Eric Holder and others will be prosecuted at minimum for lying to Congress (Roger Clemens?) and committing a conspiracy to cover-up criminal acts undertaken by our government. Of course there could be more severe indictments if Holder actually authorized F&F.
I am convinced because of Inter-Agency Coordination that this came directly from Obozo's desk. He is the one who should be charged as an accessory to murder in the death of the 2 US Agents and 300-500 Mexican citizens.
