Have you ever watch shows like CSI, Sherlock and The Bill and wondered how fingerprints and forensics work? Is it actually real? Do police really use things like that? Well, in this interview from Wired with forensics expert, Matthew Steiner, we find out that cops do use fingerprints in their investigations, but how?

Matthew walks us through some of the techniques that are used at crime scenes to capture fingerprints. There are different ways to do it, which mostly depends on the surface that they’re left on. Surfaces like glass are really easy to extract prints from. It can be done with some simple powder and a bit of sticky tape. But more complicated things like door knobs and bottles require things like castings and special dyes to be used to really bring out the clear prints.

It’s a really interesting video that brings some of the forensic scenes seen on telly to life. It’s fascinating to not only see how prints are found and recorded, but also to hear how they can be used in prosecutions. Your fingerprint hardly changes throughout your life and it’s almost impossible to remove your fingerprints. It’s clear from this vid that any criminal that doesn’t invest in a good pair of gloves is clearly a bit of an amateur (not that we condone that sort of thing).
