罗卡定律一条定律，道破必然 [ 凡两个物体接触，会产生转移现象。即会带走一些东西，亦会留下一些东西。] ——法证之父罗卡 [ 凡走过必留下痕迹。] ——法证之父罗卡 From Wikipedia, the free encyclopedia The Locard exchange principle, also known as Locard's theory, was postulated by 20th century forensic scientist Edmond Locard. Locard was the director of the very first crime laboratory in existence, located in Lyon, France. Locard's exchange principle states that "with contact between two items, there will be an exchange" (Thornton, 1997). Essentially Locard's principle is applied to crime scenes in which the perpetrator(s) of a crime comes into contact with the scene, so he will both bring something into the scene and leave with something from the scene. Every contact leaves a trace. “ Wherever he steps, whatever he touches, whatever he leaves, even unconsciously, will serve as a silent witness against him. Not only his fingerprints or his footprints, but his hair, the fibers from his clothes, the glass he breaks, the tool mark he leaves, the paint he scratches, the blood or semen he deposits or collects. All of these and more, bear mute witness against him. This is evidence that does not forget. It is not confused by the excitement of the moment. It is not absent because human witnesses are. It is factual evidence. Physical evidence cannot be wrong, it cannot perjure itself, it cannot be wholly absent. Only human failure to find it, study and understand it, can diminish its value. ” —Professor Edmond Locard
