INDIANAPOLIS -- Ajeet Singh had to steel himself for a return to work at a FedEx warehouse in Indianapolis on Tuesday for the first time since a former employee shot dead eight people, including four members of Indianapolis' tightly knit Sikh community. "I've been scared to go back," Singh said. "I don't know why this happened still. Was it random, or was it because of who I am?" While the motive for last week's rampage remains under investigation, leaders and members of the Sikh community say they feel a collective trauma and believe more must be done to combat the bigotry, bias and violence they have suffered for decades in the country. Amid intense pain, they're channeling their grief into demands for gun reform and tougher hate crime statutes, and calls for outsiders to educate themselves about their Sikh neighbours.
