Refereeing Failure

I was just thinking...

"Find a rope, find a tree, let's haaang the referee."

This sentiment against refs has always been a common thought to have while playing and spectating sports. For the most part, it is usually not directed at officiating of major league sports, but occasionally it is. Until seemingly somewhat recently.
Really, there have been problems with officiating for as long as there has been sports officiating. But, in recent history it is taken a much more major part of the game. Over the past few years there have been many instances of alarm with the officiating of games, starting with:

The Tim Donaghy gambling scandal
The biggest result of his exposure was not that he had gambled on games he officiated, but that there is favoritism based on sales, by many refs. His tell-all book exposed many other NBA refs as favoring certain teams and players, changing the way the game is played, and even the outcome. Some excerpts from this book, which I highly recommend reading, can be found here: http://deadspin.com/5392067/excerpts-from-the-book-the-nba-doesnt-want-you-to-read
If you have ever watched an NBA game that has a superstar on the team, or a team the NBA wants to see win (i.e. the Lakers) because they will generate viewership, chances are you have seem some shady calls, and become slightly if not overly upset and frustrated with the refs. I know I have. It's despicable that the game is being changed for revenue's sake. That is not the way the game is supposed to be played, and it is unfair for the teams that aren't the ones the NBA wants to win, or don't have the superstar the NBA is selling.

Instant-replay for MLB
The possibility of instant-replay becoming part of baseball has been a major debate point for years, but finally came to some realization a few years ago, when instant-replay was added for questionable home run balls. This addition has been successful, but some fans still think there should be more instant-replay used, for instances like trapped balls, safe and out calls on the bases, etc. While I agree there could be more, I am content with the current usage.

Jim Joyce and the Armando Galarraga Perfect Game
Never have I ever seen anything like this before. A safe call on a clearly out throw, costing Armando Galarraga a perfect game. Jim Joyce is a great ump, and definitely one of, if not the best in the league. But he clearly got the call wrong in that Tigers-Indians game earlier this year. Instant-replay would have been extremely beneficial here. It's the way it is, though, and it's in the past, but I mean, Galarraga lost his chance at being in the history books because of a missed call by an ump.

The Koman Coulibaly Call
This is the event that spurred me to write this entry: In yesterday's (6/18) World Cup game between the US and Slovenia, there was possibly the worst call I have ever seen. (That, and the Jim Joyce "safe" call are definitely in the top 3) The US had been down 2-0, came back to tie it at 2, and with about 5 minutes left in the game, they had a corner kick. The bouncing kick from Landon Donovan ended up going off the well timed kick of Maurice Edu, scoring the winning goal. However, the goal was immediately waved off by ref Koman Coulibaly. The original sign was that it was offside. This turned out not to be the call, and it would've been an incorrect call, had that been the call. Coulibaly refused to give explanation as to what the call was on, but it was assumed to have been a foul call. Upon watching the play over and over again on television, it was determined by everyone in the world that any fould call that was made should have been against SLOVENIA, not the US. Slovenians physically held US players back, but Edu was able to cleanly escape and score. The call was incredibly wrong, and there was nothing done to deserve it. Even the unbiased English announcers said the call was ridiculously incorrect. While it yet remains to be seen the impact of this call on the US's future in the World Cup, it did severely impact the score of the game. The US won the game 3-2, but were only given a tie. If the United States does not make it to the round of 16 because they had two ties, but would've moved on had their Slovenia tie been called a win, (as it should have been) this botched call will go down in history as the worst call of all time. FIFA, the organization that runs the World Cup has spoken about removing Koman Coulibaly from any more World Cup matches, which I agree with, but it does not give the US the win they deserved.

While I appreciate the work that many referees and umpires do, there are too many instances that should not be left with them alone. We have all this technology, which would be beneficial for the games, if used.
