I'm a referee. I see several red card incidents in this video. The game should have been abandoned.
But, what pressure is the referee under to NOT handle this as it obviously should be? Would the Association handling this league support him? Fine/ban the players? The team managers banned too? The clubs dismissed from the league including all players, and management?
I know where I live the Association is gawd awful. They rarely back the officials. Even where a crime (common assault) has happened on the pitch, with video evidence, a player didn't get banned. I got several more examples of this.
