How is it that these guys can get this info, but the feds can't? Or is it that the feds have the info but don't use it because of political pressure from office holders that have been bought?
We know that this Regime has been working closely with the Sinaloa Cartel, as has previous administrations and legacy departments. We now know through F&F that the Sinaloa Cartel is protected and helped by BATFE, DHS and the department of State.
A greater possibility than what you mentioned is that the US government through the FBI, CIA and NSA will provide information about "Anonymous" to the enforcement branch of the Cartels and then turn the other way once this information has been acted upon by the Zetas.
These hackers have not made friends with the various governments, this seems like a clean way to dispatch an enemy without having tracks leading to Holder's door.
I think you may have something there.
