Can someone answer these questions?

  In the Augusta Westland Helicopters scam, there are too many unanswered questions...

•    Why did Italian Govt not reveal the details of the investigation which it had been carrying on since two years, to India?
•    What did India discuss with Italy in this case during the past two years?
•     Why does not India try to get  the information from Italy and Britain even now?
•    Why did not the Govt of India ask for investigation by the CBI in the past?
•     Why did not the Govt of India search for other ways of getting the information after Italy refused to share it?
•    What details came out after the case was taken up by the Defense ministry?
•    What was the basis for the statement made by the Defencee Minister Antony in 2012 that no  special probe was taken up in the business deals between India and Italy?
There are rumours that the Government had stopped the purchase of helicopters temporarily after the scandal came out in the open. But the opposition is demanding that this deal should be completely scrapped . AK Antony said that he had ordered CBI investigation into this scam.
