Wild Video Of Man Using A Crocodile To Defend Himself During A Fight

What is going on here? I don't know why the hell this man has a mini crocodile at the beach and why the 2 guys are attacking him? Whatever is going on here, that crocodile is not having and willing to bite anything that is in front of him. This took place in Brazil and I know I'm not the only one who hates that it's such a short video. I want to see how it started and what happened to the crocodile at the end of this whole incident.
