Bart, that's selective editing at its worst - or best!
I didn't claim that such data existed, just that had it existed, from whatever source, if its use had prevented the outrage, there would be no complaints about sourcing other than from fellow terrorists and their friends: this ain't no game on a pitch or around a table; rules of play in these matters of mass killings are bullshit.
Neither am I saying what you feared: it doesn't matter where the data comes from, just as long as it's reliable and arrives in time. That it may or may not be used to best advantage is, in this context, immaterial, because that applies to all data, however sourced.
I agree about quality; but what makes you imagine that 'legally' acquired intelligence is the only one that is of quality? I certainly don't put much faith in the product of torture because I, for one, would admit almost to anything I have not done at first sight of rubber gloves and a set of pliers. Introduce a saw and I'm out cold, incapable of admitting anything. You see the problems with torture?
