Police in Brockton, Mass., will be the first in the country to have a powerful technological tool at their disposal — an iPhone app that allows them to snap photos of suspects and immediately learn who they are and their criminal history. It’s all part of a facial recognition system, known as MORIS, that uses biometrics to check the photo against a database of existing criminals in mere seconds.
While the novelty of technology is always exciting, I would think some serious thought is going to have to be given to when and how this app is used. Brockton Police Chief William Conlon says, “We are not going to just randomly stop people. It will be used when someone has done something.” But some major civil liberties concerns are raised here, and there is no doubt people will question the constitutionality of such an intrusive device in the context of the Fourth Amendment.

Since facial recognition is still nowhere near perfect, I’d worry also about all the false positives this may cause…
