PM should assure nation, youth: CPI on Delhi gang-rape
The CPI on Saturday asked Prime Minister Manmohan Singh to address the nation and assure the people, particularly the youth, that the government would take steps to counter crimes against women.
"If the Prime Minister can address the nation on the issue of allowing FDI in retail, why can't he find time to do so when such horrendous crimes against women are taking place," asked CPI National Secretary D Raja.
Observing that the mass protests "reflect the anger of the people" on the issue, he said the Prime Minister "should own up moral responsibility and assure the younger generation that the government would build legal safeguards to counter the menace."
He said the Prime Minister has "neither been seen nor heard on such matters. These are occasions in the history of the nation that the Prime Minister should address the people."
"His silence leads to loss of confidence. The government already suffers from lack of moral authority" on several issues, Raja said.

The juvenile boy arrested in relation to the case has spent a wavered childhood.
He ran away from home five years ago. He came to work at his uncle's dhaba here. He then did other odd jobs to make a living.
We arrested him from the Anand Vihar bus stop.
It became difficult for us to trace him because we had no photos of him and neither was there an address.
He has not been in contact with his family since last five years. He would sleep in the buses here. Only Ram Singh recognised who he was. So it became very difficult for us to trace him.
Along with his other stuff, we recovered an ATM card which belonged to the victim.
