At least in countries with a functioning criminal justice system, the verdict of a facial recognition algorithm is never going to stand up in court - the defence will demand the raw footage and put it to the jury. This technology is primarily intended for identifying suspects; an 81% false positive rate is remarkably good and extremely useful if you're scanning a train station for a terrorism suspect or a public street for a wanted fugitive. In this application, a relatively high false-positive rate is entirely tolerable (from the perspective of the justice system, at least) because checking the identity of five people to apprehend one serious criminal is a complete no-brainer.
