'An evaluation showed it was able to review the evidential material in 27 complex cases in just 30 hours - which it is estimated would have taken up to 81 years for a human to do.' Who collected the evidences in first place ? And on what basis it should take 80+ years for 1 human ? How many evidences on these cold cases ? Not so much explanations, this seems to be just a click bait to present the Sooze tool, the one "to review" the evidences.
