Were can I get one of them there Systems Lurch?
Seems to me, the principle of Garbage in = Garbage out can be demonstrated by downloading a phone book and looking for the Tea Party. The more data to sort through, the more sorters you need to read all the red flagged crap that the electronic sorter spits out.
More than anything else, this massive illegal data collection service burns up money uselessly. If the FBI and the CIA can’t stop two Kid bombers when they are red flagged and reported by other agency’s, how the heck are they going to accomplish anything trying to transcript the worlds telephone conversations?
Reading other peoples mail is what perverts do, to about the same effect.
Would be interesting if someone was actively working on a public data pollution initiative to make mass data less reliable, though it might have the unfortunate effect of actually disrupting legit law enforcement.
