China Hosting 2008 Olympics

What's all the blah blah about China hosting the 2008 Olympics in Beijing? Wasn't the venue long decided before the start of 2008? Why wasn't something done about it before the actual time of the games (if there are issues refuting the venue)? Is it important to question it's legitimacy now?
Are there particular criteria for deciding where the Olympics are held? If there are, please post them so that the public can have access to them next time. I believe that all this all this international spotlight may lead China to make many improvements in areas needed. Who the hell will be paying much attention to China's pollution, or human rights affairs during the games?! All normal people will be focusing on the games and the medals! (I hope so, because if not...).
My discourse is about foreign journalists not being allowed in the Stadium at certain times during the hosting. Why? Next, I am very annoyed about the thousands of citizens who were apparently evicted forcibly in and around Beijing to make room for the construction of the facilities for the Olympics. This I don't agree with. This is sad,especially if the victims were not compensated sufficiently.
Isn't there pollution EVERYWHERE? China has been condemned by some other nations to be very polluted. Well, despite this, China is considered to be a country with one of the fastest-growing economies in the world. At least give them some credit for that. China is a developING nation. This means then that there is room for improvement because they are a 'work-in-progress.' All developING nations have issues of some sort. (Matter of fact, even the developED nations have issues to contend with; some are even greater than China's.) Agree? Please, China can be given the chance to improve/prove themselves. Maybe the other nations that are concerned could try to provide assistance or the necessary resources that China will need to correct all the flaws being debated about them.
Some folks suggested boycotting the games. Hah! Wouldn't this be worse than having it in China? All the wasted training, disappointments and wastage of money and other valuable resources? We all would have been affected one way or another. What if the 2008 Olympics were being held somewhere else? Wouldn't there be new complains and contentions? I have a SUGGESTION. Please host the next Olympics in my hometown,...JAMAICA (West Indies)! Just as I thought...(new contentions?) Stop all the blah blah and get on with some action!
