"Only 30 people have been convicted for these crimes, with police and prosecutorial authorities failing to bring government and party officials allegedly involved to justice," a number of Sikh American organisations said in a letter to the US President yesterday.
"Given the important role that India is poised to play, and is increasingly seeking, in setting international policy -- potentially as a permanent member of the United Nations Security Council -- we urge you to address impunity for the 1984 premeditated violence in your engagement with India," the letter said.
The letter further says that "organised massacres" followed the assassination of Prime Minister Indira Gandhi by two of her Sikh bodyguards on October 31, 1984.
"However, the entire Sikh community was targeted in retribution, while the Delhi police largely did nothing to protect them," the letter said.
"Although the government promptly convicted and executed those responsible for conspiring Gandhi's assassination, it has allowed most of those responsible for the anti-Sikh violence to elude prosecution, owing to flawed investigations, intimidation of witnesses and the destruction and suppression of evidence by police officials," it said.
