Watch some Brazilian policemen fighting with several scoundrels in the middle of the street in a generalized brawl.

In Brazil, the police cannot shoot while the person approached is unarmed. If the citizen approached by the police officer is unarmed, the police officer is not authorized to use lethal force. He must use the bat to control the situation. That’s why no cops shot the bums, but if only one of the bums had been armed with a knife (blade gun), the cop would no doubt have shot to ensure his safety and that of others.
