I watched an interview recently on SIkh Channel from Delhi, with Bhai Gurcharan Singh Babbar. He also did an interview a few months ago on Sikh Channel in the UK.
He says he has spent most of the past 28 years trying to get justice for what happened in Delhi in 1984, and speaks very emotively and powerfully. I plan to watch it again from the beginning
He was also promoting his book 'Indian Governement Organised Carnage, Nov. 1984', which is also in Punjabi.
I didn't know anything about him until recently, but it seems he has written other books about 1984, and has been doing a lot to get justice.
There are some videos of an interview/discussion with him on youtube:
Can any of the Sangat enlighten further about this personality, and the books he has written?
