Czuch Chuckers: In my opinion, referees have been a major problem of all previous World Cups. Compared to the 2002 one, I think we're seeing a slight improvement, even though it might not seem so at first sight. We have to keep on mind that referees are humans just like all of us and they do make mistakes. It's up to the FIFA officials to select the best possible referees who make the fewest mistakes, which task they seem to have failed in many cases. But as I said, I see an improvement this year and I believe it's going to get better and better. I believe that your blank statement "the officiating has been poor" is wrong, since there have been many games which were officated very well (GER-CRC, GHA-CZE, ITA-CZE, etc.), on the other hand there've been some which come close to the KOR-SPA game from the last World Cup. Today's ITA-AUS game is a good example of that.
As far as your proposal for a change of rules concerning the red cards, I'd let the rules stay the way they are right now. In my opinion, the problem is not in the rules, it's in applying them on the pitch.
