Did anyone actually RTFA? The part about Anonymous and what I read from the rest was pretty much common sense. Didn't try to make terrorists out of kids, and the only obvious "scare tactic" I found was that they had red headers in the pdf. I actually feel better knowing somebody is keeping an eye on things, just in case.
That being said, I think I understand a bit more about why there is a need for active watchdogs to supervise the police. Given their job they cannot sympathize with the organizations they investigate - and if they do it's likely they won't do their job right. Everything they see or hear about say, an animal rights group is through the perspective of possible trouble. And it is as it should be, that's what they are being paid for. But you cannot let the same people also guard personal rights... and the fault for the consequences belongs to whatever politician thought it was possible.
