How long for Radia?

With former Telecom Minister A Raja already under arrest how long will it take the government to get cracking on Neera Radia?
It seems a bit longer than usual. Which again goes to point that she is connected far more than the former minister who has already been arrested. Her connections with the Tatas and the Reliance group seems to be going a long way in securing her freedom for now. But for how long? And how long before the eminent journalists that have been named in the scam will be questioned?
There is a need to question each and everyone that been in touch with the major players of the 2G scam. And Darkha or Charkha Butt and her erstwhile close male friend need to be questioned in detail by the investigative agencies to bring out the complete conspiracy.
