So for everybody that says that various intelligence agencies collecting all kinds of information isn't bad, because they'll never use them politically: here's your answer. You'll never know whether or not this information was used politically, because what they'll do is 1) find the person, 2) find the crime, 3) construct the evidence chain so that it doesn't reveal methods. I don't think "evil" begins to cover it. Given this operational scenario, you'll never, ever catch the government using intelligence information for political reasons. Even if the practice is widespread. (And, for the record, I'm all for law enforcement, and law enforcement keeping intelligence files on people who may be dangerous. This collection does not include the scenario I outlined above)
