On a warm July night two years ago, Moninder Singh received a chilling message from special federal agents who showed up at his house in British Columbia: You are being formally warned that there is an imminent threat to your life. Avoid public spaces. Enhance security at home.
The first person he called — a friend and fellow activist in a campaign promoting an independent Sikh homeland carved out of India — had just gotten the same ominous warning.
A year later, that friend, Hardeep Singh Nijjar, was dead.
