Un jour, ça finira mal

In this investigative account, Valentin Gendrot documents his six-month immersion as an undercover recruit within the French national police force. He details the daily mechanical operations of a precinct, from the psychological fatigue of officers to the specific instances of administrative negligence and physical aggression he witnessed while wearing the uniform. Gendrot identifies a culture of silence where systemic misconduct is shielded by internal loyalty and a lack of oversight. He provides concrete examples of how resource shortages and high-pressure quotas contribute to the deterioration of police-citizen interactions in marginalized neighborhoods.

This book is intended for readers interested in criminal justice policy, sociology, and the mechanics of state institutions. Those who follow institutional reform will find a detailed portrait of the friction between law enforcement and urban populations. Readers walk away with a functional understanding of the training gaps and mental health crises currently affecting the French police. The text provides the specific evidentiary framework needed to discuss the structural causes of police violence and the logistical failures of the current security apparatus.
