I had an idea a few weeks ago, I don't know if it's been considered but I think it'd be a good idea, I was wondering what other people thought about it. Say for instance a player does something violent during the first half of a game that is televised, but goes unnoticed by the referee and touch judges but the cameras catch it. I'm talking about indisputable acts of violence/bad sportsmanship that only the cameras catch and none of the officials. Do you think it'd be a good idea for referees to yellow or red card players during the half time break so they can't take place in the first 10 minutes or even the whole of the second half? I think it'd be a good idea, but for only the most violent of instances.
