Police and prosecutors are eager to use anything they can to identify a suspect and obtain a conviction, especially in the most serious cases, such as California homicide crimes. However, often this comes at the expense of—rather than the pursuit of—justice.
For example, take a recent New York Times article discussing the use of facial recognition software. Racial recognition software relies on computers to recognize human faces. In the law enforcement context, this usually involves a police officer inputting a suspect’s photo into the program, which then searches through a database of thousands of photos, looking for a match. Police will occasionally use facial recognition software if they have surveillance video or a still-frame photo, but do not know who it is in the photo.
According to the New York Times article, the use of facial recognition software was used to arrest a man for a crime he did not commit. Evidently, police received a report of a man stealing candy. When police arrived on the scene, they found the suspect at a rental car agency, trying to get his rental extended. The suspect gave them an ID card, apologized, and offered to pay for the candy.
