This week, we revisit a piece from last spring, which took you inside an alleged killing-for-hire plot by the Indian government, including the exclusive video of the last moments of Sikh activist Hardeep Singh Nijjar before he was gunned down outside a gurdwara in Surrey, B.C. The RCMP now says there is "irrefutable" evidence that the government of India was behind his killing. Four Indian nationals have been charged.
