Police regularly try to pressure rape victims into marrying their rapists, or accepting a cash settlement. See below link to another case a few days ago. The problem in India is society's treatment of women and India is among the very worst places in the world for a girl or woman to live. Somalia and Afghanistan are often considered safer places for females to live than India. The level of unreported violence is staggering and shameful. Until this is widely accepted and acknowledged, by more than a small minority cross-section of Indian society, little will change in India.

Your point is useful insofar as we recognize that the police are dominated from a particular subset of society--those who condone marrying rape victims to their rapists, for instance, implicitly by permitting it or explicitly by encouraging it.
Thus, it's something that needs to be dealt with, and perhaps that is an avenue to explore to find a solution.
The analogy with enforced birth control is a poor one. This issue is about creating a civil society where laws are enacted and enforced for the protection and well-being of all citizens regardless of gender, caste, sexual orientation, economic status etc.
In a modern society, the state has a duty to protect innocent persons from harm. So far, India has been stunningly inept in this area.
