Also, whenever a government really wants to do something, they'll use any excuse that's available. For example; PATRIOT ACT, DMCA, Iraq Wars, etc. etc. For cyber-security, if none of this Anon or LulzSec stuff happened, it would be Russian or Chinese hackers that are infiltrating and by god we must protect Americans from those evil foreign hackers. Or they would rely on the terrorist excuse: the terrorists are losing in real life so they need to re-build support and attract younger people so why not hack some sites and gain new supporters that way? Beheadings and suicide bombings really fuck up the recruitment rate for terrorist organizations.
See how easy it is to come up with an excuse that the internet needs to be locked down?
