Although Portugal is a calm and peaceful place, its police force is not on a par with the rest of Europe. When the law enforcement arm of a society is too weak to perform its mandate of protecting that society, the mob rules. The lesson can be applied on all scales of events, even worldwide. Without the United States and its professional law enforcement, including its military, the Islamic terrorists would be taking over our society, en masse, and our neighbors, Canada and Mexico, would be about as much help as the neighboring suburb Cascais was to Carcavelhos, Portugal. Without the strong arm of vigilant defenders, "the mob rules", whether that mob be a band of teenagers, or a barbarous cult of murderers.
