There is much evidence to suggest that the decentralization of violence predicted in "Beyond 2012" is already underway. While Guzman and Lazcano remain big names, the relative power of the capos of their stature has been reduced during the Calderon years, ebbing away thanks in large part to the rise of smaller, more regionally isolated gangs.You can (and should!) buy the book here.
Some of these form from the ashes of larger groups, like the Mano con Ojos (an offshoot of the Beltran Leyvas) and the Caballeros Templarios (a splinter from the Familia Michoacana). Others, like the Zetas, start as simple enforcer groups but evolve into something very different: perhaps the best example of this phenomenon is La Linea, a Chihuahua gang that has essentially subsumed the Juarez Cartel, its initial sponsor.
There are also innumerable local street gangs, which, though they have existed in some form for decades, are now more violent and more connected to the transnational groups than ever before. While the principal driver of violence in Juarez appears to be fighting between the forces of Guzman and Carrillo, local gangs are a significant factor in sustaining the bloodshed: Mexican authorities have estimated that there are up to 1,500 street gangs operating in Juarez alone.
There are even questions of the degree of control that Lazcano and Guzman exercise over the organizations they lead. "Beyond 2012" mentions rumors of a divide between Lazcano and his number two, Miguel Treviño, and as InSight Crime has pointed out, it appears that many of the most spectacular acts of violence perpetrated by the Zetas were not orchestrated by the Lazcano and Treviño, but rather by lower-level members. Guzman’s control over the Sinaloa Cartel appears less frayed, but a wave of violence last year in Durango -- a state long controlled by Guzman where hundreds of bodies were discovered in mass graves last spring -- was attributed to infighting among Sinaloa cliques.
Also, SOPA seems to suck: when Boz, Richard, and Wikipedia are all lined up on the same side of an issue, chances are that's a good place to be.
