How has fingerprinting helped in CSI?

There are thousands of examples that I can give you as to how a fingerprint helped identify a criminal. Let me give you just two. There is Lee Harvey Oswald, who left his fingerprint on a weapon that was fired from the Texas Depository School Building. There is also James Earl Ray, who left his fingerprint on the weapon that was used to kill Martin Luther King. There are literally hundreds of thousands of other examples that I can give you. Fingerprinting is the most important and potent investigative tool that criminal investigators have.
