'Anonymous' and Privacy on the Internet

With hangings, beheadings and mass murders, drug cartels have created a culture of fear in Mexico, which extends even to the Internet. A YouTube video that went viral has drawn attention to a cyberspace collective calling itself "Anonymous." By threatening to expose civilians connected to the murderous Mexican drug cartel, Los Zetas, did Anonymous reveal a strain of vigilante justice or just an elaborate hoax? The incident is just one example of an Internet subculture that provides an outlet for discontent and the power to raise havoc in both cyberspace and the real world. We hear about the evolution of "hacktivism," the "hivemind" and the controversy about anonymity and security on the Internet.
