I'm saying that police departments DO have databases filled with images that have wooden walls and such. Not furniture usually, but photos are often taken in sub-optimal circumstances even when the police or others are trained to take the photos properly. I know this is the case because I've worked on biometric systems for the past 18 years, and I have personally worked on a system which was identifying almost every face to a mugshot taken against a wall with wooden paneling and the matching algorithm was keying in on it as a face rather than the human. I'm not speaking theoretically, this is how these systems fail.
