Regardless of the outcome, 'wise' ones will figure out ways to get around. This will be no better than picking low-hanging fruits. I'd buy that it can be a short-term deterrent approach to discourage some. BTW, 'TOR' was a bad example, in this context. Whoever is determined to monitor the onion router jumble, I wish them good luck! I personally don't like TOR, because it takes away my user-experience by terribly slowing things down; but I admire the way it works; and people use it for many reasons besides 'evil-work'. I don't see a direct link between CISPA and the use of TOR.
