So what they mean is they can't track *suspected* criminals anymore. Suspected should mean nothing. Anyone could suspect anyone of anything, and say it loudly enough it can become true. I want evidence not presumption and if there's enough evidence of a crime having been committed then it should be trivial to obtain a warrant and poke that under the noses of communications providers.
They overstepped the limits of the legal framework, just like the baddies. And they know it.
Normal law-abiding peons and suspected criminals/transvestites/activists/terrorists/ghosts/aliens/jobsworth civil servants have got themselves their very own technological equivalent of the Wilson Doctrine. Seems only fair to me, even if I don't like the fact that bad people do bad things. Hurrah for normal law-abiding peons and suspected criminals/transvestites/activists/terrorists/ghosts/aliens/jobsworth civil servants everywhere!
