Speechless shock

The seven o’clock news by NHK made me really shocked. After the Tohoku earthquake, there have been a lot of things that made me angry with the government, TEPCO and the committees for nuclear power, such as the Nuclear Safety Commission and the Nuclear and Industrial Safety Agency, but today’s news was the worst ever for me. The news was about the Nuclear Safety Commission (NSC). In today’s committee of the House of Representatives, the chairman of the NSC revealed that when the earthquake occurred, only a few investigators for an emergency measure were assembled on that day even though they have forty investigators. That’s because the NSC tried to contact them on with emails to their mobiles but they could not contact almost all of them and some who could receive the email could not get there because of stopped transportation. So, only a few people who were able to walk could gather at the office. What were their contingency plans? 
Furthermore, the NSC is supposed to dispatch the investigators to the spot immediately, but they dispatched only one member of staff. They didn't dispatch the investigators until a month after the earthquake. I couldn't believe it. For the clumsiness of the NSC’s response, the chairman said that he thought they had failed to respond well enough, and this reflected on themselves. As I heard it, I was speechless at his statement. 
As I mentioned before, there have been a lot of problems, but I thought they had tried as hard as they could but just not in the right way. However, the NSC did nothing. I understood why many people doubted the significance of the existence of the NSC. I want them to say that they will give back their remunerations and contribute them to the people who have suffered. I heard they received over ten million yen a year. 

It was too difficult for me to write about a thing like this. I tried to write it by consulting a dictionary. I wonder how far I can say what I think.
