The Dutch have come up with a new way of catching criminals, that’s even better than fingerprints, it’s called smell prints. Apparently, each of us not only has one unmistakable fingerprint and DNA, but we also have a unique scent that is identifiable. In solving a crime, the police can retrieve an article used by the perpetrator (such as a gun), and extract a smell print from the object in as little as 20 minutes. The smell can then be stored for as long as 4 years. Once a suspect is apprehended, he is asked to wash, and then handle a cloth for a few minutes. The cloth is then placed in a line up and a specially trained dog is given the original smell print to examine. The dog is then asked to identify all the smells in the line up. If the dog finds a match, he barks at the container identifying which one. To make the evidence admissible in court, the process is repeated but this time without the suspects smell. This new crime fighting tool has solved hundreds of cases in Holland, and they are now starting to archive known criminals’ smells to compare against outstanding crimes.
