How are fingerprints helpful in crime?

Fingerprint ridges differ from person-to-person, so if an offender were to touch a window at a crime scene, those fingerprints could (potentially) be traced back to him. That being said, a majority of fingerprints are only partial prints, and generally don't give as much information as crime shows like to believe. However, fingerprints can be useful at including and excluding potential suspects. If a detective has the offender's fingerprints at the crime scene, but his potential suspect's prints do not match. He is obviously investigating the wrong person.
