Brain Fingerprinting
The world is safer for law-abiding citizens, thanks to Brain Fingerprinting (BF), a way to peek into a suspect's mind to verify if he was at the scene of a crime. How? Sort of like a lie detector test, but BF reads a person's involuntary response to a memory. It measures and records specific brain waves that are only active when a person has memories of an event or place. If those brain waves don't register, the person doesn't know about the crime. If memories of the crime do show up, the criminal is busted, and the streets are safer.
