Yeah, they have been in sleeper cell mode for a while, but also realize that false flags can work in the other direction. The feds did not shed many tears over Brian Terry getting killed by the drug cartel which had allied by the FBI and BATF, they won't shed a tear if a car bomb attributable to some Jihadis blows at a US/Mexico border checkpoint and causes the heavy militarization of the border.

Think about the win win win that goes on within the alphabets and their favored cartels. A seriously shut down border would mean exclusive profits for the cartels which operate tunnels and keep their bribes paid. The little backroom deal being that shipments of dope get allowed through for a price as long as the tunnel operators keep WMDs out.

The ultimate shakedown "let us run dope, or we will step aside and let a few WMDs in". The ultimate of the ultimate protection rackets.
