Lamentably but inexorably it is affirmed, perhaps every day more, the rise in power of the violence in the socio-political environment of the majority of the States in the world. Certainly, neither the disturbance to the social order nor the trauma on the personal level of the victims of these antisocial acts will participate to elude the gravity of this aggression to the morals of civilized societies. However, in many cases and paradoxically, the perpetrators of these acts escape the repressive system because of a lack of evidence. The context seems to justify in the legislations, the development of a body of rules able to regulate in an adequate way, the criminal situations with obvious character. The Cameroonian legislator is not left out, through Law N° 2005/007 of July 27, 2005 on the Code of Criminal Procedure. This law innovates precisely by reforming the organization of the procedure of flagrante delicto. Curiously, since its adoption, the procedure of flagrante delicto seems to have fulfilled very few expectations, despite the eminently coercive character that distinguishes it from the ordinary investigation.
