no change can take place by formulating/enactig laws.these are there since last 100 yrs and more.Then solution!change at indivisual/family/social level.please imagine a situation-the parents take a decision that if their son/daughter take bribe,we would show them the door n the parents of girls decide that they would not marry their daughters to corrupt govt.officials.but,Alas,the situation is reverse.people are more affectionate to corrupt children/son-in-laws,and you talk of change.
