An objective and comprehensive book which evades any issue related to the police, since the origins of his birth to the present. And beyond its rich historical details, I retain this book its tone, rigorous but generous, studious but pleasant: the author does not lapse into caricature or in partisanship. The book, through an extremely thorough study and punctuated by numerous facts or anecdotes, simply recall the merit of what was, what is, and what will be the gendarmerie: a military institution dedicated to the protection of the French state and its civilian population.
