Akash Banerjee isn’t sure whether he’s allowed to talk about the BBC documentary India: The Modi Question on his YouTube channel. The documentary examines Prime Minister Narendra Modi’s alleged role in deadly riots in the West Indian state of Gujarat in 2002, and the government has worked hard to keep Indians from watching it. Screenings at universities have been banned; in one case, students said authorities shut off electricity and the internet to stop it being shown, and clips of the documentary itself have been removed from Twitter and YouTube after the Indian government cited controversial emergency powers.
