Investigating a crime and trying to prevent it means evaluating every possible voluntary and involuntary message left by an author. We can accept this concept if we start from one of the most important axioms of communication, “it’s impossible not to communicate”. Moreover, if communicating means acting, moving, influencing all human behavior, the communication process can therefore not be considered within the criminological sciences. Criminological communication could be an important tool to analyze crime for human sciences in our digital era.
