New Delhi: Prime Minsiter Narendra Modi said on Friday the country`s head hangs in shame whenever there is news about rape. "Our heads hang in shame when we hear news about rape," Modi said while delivering his maiden address from the Red Fort on India`s 68th Independence Day. He also asked parents to question their sons about the malaise. "After all, a person raping is someone`s son. As parents, has anyone asked our sons, where is he going? Why not put the same yardstick for sons too," he added.
