Detectives Use this Simple Technique to Find Your Fingerprints (Even AFTER You Have Wiped Them Off)!

The video tutorial explores the science of fingerprints, their uniqueness, and their role in forensic investigations. It explains how fingerprints are formed and the exchange principle, which is crucial in forensic science. The tutorial covers the three types of fingerprints: patent, plastic, and latent, and the methods used by crime scene investigators to detect and lift them. Techniques such as fingerprinting powder, ninhydrin, cyanoacrylate, and vacuum metal deposition are discussed. Advanced methods for visualizing fingerprints on challenging surfaces, including electroactive films and bullet casing analysis, are also highlighted.
