Law or changing the mindset? What's the solution?

Finally, I have internet at home and, hopefully, I won't be traveling soon! I am now in Houston and will start the ground work for Unchaahi here within the next month. I'll keep you guys updated. In the meantime, here's a well made video that you must have a look at. Embedding is disabled for the video; therefore, I can't post it here. However, do watch it on YouTube itself.

A woman in the video says, "beti hoyega to kaat daalne ka". hmm.
Translation: If it's a girl, then she's to be cut off (killed).

Some issues brought up in the video:
1. Female foeticide is a well-organized crime wherein doctors and politicians are collectively involved because a lot of money can be made in this field owing to the girl-hatred in the societal mindset.
2. Changing mindset is required but cannot be the only solution since the change is unaccountable.
3. Criminals (doctors and politicians involved) must be convicted of their crimes. (but is it even possible in a country where no law is ever implemented?) PCPNDT act has long been in place but it has had no positive effects. What's the use?

Law or changing the mindset? What do you say?
