It's Russia so I'm not suprised something crazy happened at a wrestling event. Maybe two years back they had a brawl between coaching staffs that turned into a crowd fight. At a junior or cadet event about a month ago they had a multiple coaches/parents pull guns in each other. If all that happens is a protest by one region that stops the competition then I'd say they are handling it relatively calmly at the moment. But, I wouldn't be suprised if something occurs later too if they feel slighted again. They take their combat sports seriously in Russia, especially around Dagestan.
