All evidence disappears

In the 2 G Spectrum scam the CBI could not get vital evidence against Raja as the same is missing. The government ensured the sufficient time is given to Raja to dispose of the evidence before initiating the CBI enquiry. So Raja goes scot free and the Government can claim that the CBI could not prove the case hence it is blame less. The shame is on the opposition and not the ruling congress. The opposition does not represent the people. They should boycott the budget session and continue insisting on JPC.
