Nanotechnology has the potential to literally take over the future of law enforcement. Nanotechnology is a way to register your DNA (Deoxyribonucleic Acid). It is most commonly used in fingerprint scanners, and it can improve everything from bullet proof armor, to the effect of the actual bullet on you. This technology works when it comes in contact with the target, and it shows evidence of the crime scenes by using the DNA. Biological technology can help nanotechnology. Nanotechnology can potentially help law enforcement in hope of less risks of threats and control outcome.
