A divisive iPhone add-on from BI2 Technologies is about to reach police in a way that could challenge civil rights. The MORIS case, already used in the military and a few limited areas, will let officers snap a photo of a person's face from up to five feet away and automatically cross-check it against a police database to see if it's a known suspect or if the person has a criminal history. If they have strong reason to believe a person is a suspect, they can even scan the iris from six inches away.
