Our brains have always been our most private sanctuaries, a place where we store our innermost thoughts, a place where our secrets safely hide, inaccessible to the rest of the world.  But a revolutionary new technology could change that, by reaching into the deepest recesses of our minds and pulling out the truth.  Brain Fingerprinting is a portrait of this new advancement, a powerful forensic tool that may far surpass the accuracy of the polygraph test and permanently change the way criminals are convicted – and freed. With the seeming ability to tell from brain waves whether a person is lying, Brain Fingerprinting is considered by both the FBI and CIA to potentially be one of the most significant breakthroughs in crime detection since the advent of DNA analysis. Is the technology all it’s cracked up to be, or are there other, more promising techniques in the quest for the perfect lie detector?
