Q: Why is defense ministry against Lok Pal bill?
A: This is not simple.
If strong imprisonment is implemented for every bribery, there may hardly anyone be left to run the country of 1.1 billion! Even current semblance of governance may collapse and the country may plunge in chaos typical to our neighbors.
This may be a conspiracy to destabilize the country by foreign (but not Italian or erst-while Italian or even half-Italian) hands.
