...apparently in protest of the immigration law passed last year.

Yeah I probably went a little overboard with the LulzSec posts... . I guess my point was to drive conversation about what we are considering ethical hacktivism. I agree what LulzSec is doing in illegal. But wasn't it also illegal to set up proxy servers that allowed the Egyptian protestors to coordinate using facebook and twitter. They were violating the law of the land to facilitate their right to protest. Do we consider that ethical hacktivism? How do we protest in the digital era? Is there even such a thing as ethical hacktivism if a "hack" is considered an act of war?

These are very valid questions.  This is the main issue I have when people use a black/white definition when it comes to defining "ethical".  I usually find that when people refer to "ethical hacker" they mean "lawful hacker."  But not everything that is lawful is going to necessarily be ethical.  Case in point being the exact example jsm725 gave: setting up of proxy servers for Egyptian protesters.
