You do not give a clear indication of your country. How you feel about the handling of suspects and trials and the imprisonment of those who are guilty will be a large input. If you're in a country where the act of arrest is itself brutal, that alone may be enough to put you off. Again if you think that people won't get a fair trial or if they do and yet face horrors in jail then maybe it will put you off. However the counter side is to explore could this be a source for good overall. Clearly you shouldn't be naively over optimistic but is it plausible this system may improve matters over the current situation? If a number of innocent people are currently arrested by biased store detectives then a system that highlights a higher portion of genuinely guilty people would be a positive.
