Basically, locards exchange principle or theory, simply put is: there is no perfect crime because the culprit always took something but just as likely, left something behind which may eventually lead to his/her identity.
It actually more says that when two surfaces come in contact, there is always an exchange of material. Whether you realize it or not. It really has nothing to with crime in particular. Take it from me, I'm a crime scene technician.
Locard's principle of exchange states that every contact leaves a trace. This means that when two objects come into contact with each other, there will always be a transfer of material, such as fibers, hairs, or skin cells. This principle forms the basis for forensic science and is often used to link suspects to crime scenes through the analysis of trace evidence.
