The book “grew” from the chapter of the same name in the famous “Monkey Upgrade” by Alexander Nikonov and develops its main ideas: the legalization of firearms is the most effective way to combat armed crime, which is becoming increasingly widespread. This book is not only and not so much about weapons and crime. The book is about stupidity, because of which the civilized world loses thousands of human lives every year. Actually, opposing stupidity from the standpoint of common sense is the central theme and main goal of the writer’s work, which he strictly follows in all his works. The author’s argument in the polemic with the “banners” of weapons, based on extensive factual material, is so convincing that it leaves no doubt: citizens should not be deprived of the opportunity to defend their own lives and the lives of their loved ones.
