I don't know why CBI raids yrs after a big scam comes to the knowledge of people or it is ordered for the investigation of a corrupt politician, bureaucrat, media person or a industrialist. nothing incriminating could be searched from offices and residences after a year. The recent example being Raja & Radia Raids. Another example is CWG & Suresh kalmadi, I don't know why CBI is waiting for to raid kalmai & even interrogate him?
