I just stumbled upon this by luck. In a 2012 blog, Target wrote about their crime-fighting ways. They have an actual, honest to goodness forensic lab, just like on TV shows, but without the dramatic music.

Oh, and they help law enforcement on outside cases...

Target has a top-rated forensic services laboratory that provides forensic examinations, and assists outside law enforcement with help on special cases. Target’s lab is among 390 crime labs accredited by the American Society of Crime Laboratory Directors/Laboratory Accreditation Board (ASCLD/LAB), which underscores Target’s commitment to quality forensic work.

Oh, part two - They have TWO of them!

Based in Las Vegas and Minneapolis, the forensic team helps solve organized retail crimes committed at Target stores through video and image analysis, latent fingerprint and computer forensics. The team also tackles felony, homicide and special circumstances cases for law bureaus that need the extra manpower, facilities, resources and time – free of charge.
