Wow, this is getting real, very quickly. This is a very, very different enemy than taking on a corrupt government, who still needs to stick by some sort of rules.
Assuming that this really is an Anonymous-supported act, I'm not sure if this is an enemy they want to engage. If they do end up taking on a drug cartel, do they really know what the consequences of this will be? I think Anonymous really needs to think deeply about the consequences of releasing names that would most certainly result in the loss of life.
