It's an irony that Anti-Sikh riots took place in 1984 despite a Sikh being a president then and the culprits were left scott-free in 2013 despite a Sikh being a Prime Minister now.
Justice Narula committee was formed by the then BJP government within days after taking office in December 1993. It was a BJP initiative that formed Nanavati Commision in May 2000 by the then PM Shri Atal Bihari Vajpayee. It was the congress and their leaders who were either directly involved in the Sikh killings or supported the killers. Still no senior congress leader has ever gone to Jail in last 29 years despite having witnesses and credible proof.
Congress government has failed on all fronts including corruption, scams and non-governance. BJP had opposed the appointment of CBI director Ranjit Sinha even in 2012.
