Abstract
This work deals with the relationship between the State and crime, to which end several suggestions are made to achieve a general organizational framework that is appropriate for the Judicial Police. In addition, it examines the general functions it should have in the criminal process, the limits of police investigation and its consequences; likewise, it addresses some complex aspects of police action as a public authority, when acting in the prosecution of crime at the present time. Finally, it points out the minimum common aspects that should make up an effective police model, both from a material and a purely legal point of view.
