The anguish found echo in the Rajya Sabha too.

Samajwadi Party's Jaya Bachchan broke down in the house saying she wondered what would happen to the girl's family, while Trinamool Congress' Derek O'Brien said as the father of a teenaged girl he was scared.

Bachchan also said rape should be treated at par with attempt to murder.

"I stand here nervous and scared as the father of a 17-year-old daughter," O'Brien said.

"Rape is not just a women's issue. It's about men who stop behaving like human beings and start behaving like animals," he said.

As the members after members expressed outrage, Home Minister Sushilkumar Shinde said the Delhi gang-rape case will be tried by a fast-track court with a request for daily hearings.

Former women and child development minister and now Congress spokesperson Renuka Chowdhury hoped that the gang-rape would not "remain a mere statistic."

The National Human Rights Commission (NHRC) also issued notice to union Home Secretary R.K. Singh and Delhi Police Commissioner Neeraj Kumar, saying that the incident was a "grave violation of human rights".

Outside parliament, analysts tried to make sense of what had happened, the psychopath edge of the crime that gave it its bestiality.

Saying that this was a sociopathic crime, psychiatrist Sanjay Chugh told CNN-IBN: "The mindset of the perpetrators of gangrape is an amalgam of mob/herd mentality, disinhibition, utter disrespect for social norms and a certain knowledge that the so called protectors of law will either turn a blind eye or can be pressurised or simply bought with a certain sum of money."

Carrying slogans like "mere skirt se oonchi meri aawaz hai", Delhi's women - and men - who demonstrated this Tuesday asking for exemplary punishment like hanging or public hanging, agreed.
