I agree with the security parts completely but giving access to revenue departments is complete bull.
Last month an MP and a state cabinet minister from ruling Andhra Pradesh govt got their businesses raided by IT, EC & RI. It turned out that each of them has created suit case companies and transferred 10,000 crores each to accounts abroad.
Also presently the agencies got issued a look out notice from the court to all airports that they might jump from here.
PS: Half of the money which they both amassed are from loans from several nationalised banks across the country.
The centre is of the opinion that this fiasco might turn out into another Vijay Mallya affair and also informed the interpol before hand.
Now tell me how come the centre knew about the transactions they made or were making. Through this surveillance techniques only.
We the comman man aka aam aadmi is now where threated by such National Security Acts because we know very well that we are the hardworking Janata and innocent. It's those guys who does such unscrupulous activities who are always afraid or feel threatened by such surveillance by the central agencies or even the local state ones for that matter.
