Did you mean the hackers or the police? (Homeless people pay sales taxes, and many aren't criminal either. Still, the police find it necessary to murder them from time to time.)
I meant the hackers. What the police did is indefensible.
Stuxnet: I bet the Israeli government was behind it. It was the first virus to affect a "real-time" process (centrifuges in Iran). It entered Iran through the lab software provided by a (Russian?) contractor who helped build and supply the weapon-refinement facilities in Iran. I am pretty sure it set back Iran's efforts toward having nuclear weapons by years. At least I hope so. I don't think even this "Anonymous" group could have done that, and if they did, they probably would have taken credit for it.
I guess I thought I would sweeten the pot / expand the scope and make even ~more~ complicated the questions of ethics, anonymity, hacking for social justice and the role of technology in our worldwide village. LOL
