It shouldn't really matter what the accuracy of the software is being used properly. The facial recognition software should be used as a tool to help narrow down potential suspects. It shouldn't be the judge jury and executioner to decide if someone was indeed at the scene of a crime. The officers using the system need to be properly trained to understand the limitations of the system. For example just because the system finds a close match, it is only searching a database of people it already knows about. The actual suspect may not be in the system. Traditional police detective work still applies. The face match is just a lead not hard evidence. Also, the systems use should be public (just like the police's use of fingerprint biometrics is). Problems come in when you try to use this or any technology to automate law enforcement. Human judgement and police work need to always be part of the equation. Facial recognition should be thought of as a username not a username and password combination. It shouldn't be the only piece of evidence in a case to prosecute.
