I don’t know what it is about Brazil, but there are many publicized, documented and videotaped incidents of mob violence in Brazil. You’ll see stories about how a mob killed an alleged child molester or rapist in Brazil (complete with a video). Or how a mob caught and beat a thief (once again, complete with video tape). Or how prisoners beat and killed a child molester in jail. Its brutal justice. For some reason, you see it coming out of Brazil more so than other countries, or at least publicized in Brazil more so than other countries.
When the police won’t police and the government won’t protect, people have to take the law into their own hands and organize collectively on as large a scale as they can to protect themselves and their families. No choice. Law of the jungle.
