Who are the Sikhs for Justice? I didn't know either. From their website:
Sikhs For Justice (SFJ) and All India Sikh Students Federation (AISSF) has launched an international campaign to have United Nations investigate the killing of Sikhs in 1984 and declare it Genocide.
The 1984 Yes It’s Genocide campaign will obtain more than 1,000,000 signatures requesting the UN to independently investigate the organized killing of Sikhs. It is clear that India is unable to objectively investigate itself.
After almost 3 decades and 10 Commissions, India is no closer to figuring out who organized the killing of Sikhs. One thing everyone agrees on is that the killing on Sikhs were indeed organized and well planned, as stated in Justice Nanavati’s Report.
Many academics, politicians and media personal have been given false narratives to the point where only a handful of people know the reality. The killing of Sikhs during 1984 was not spontaneous anger. The Indian Government's Commissions has proven the same.
