Canadian PM Pressed on Slow Progress in Nijjar Murder Probe; US Hints at Possible Indian Agents' Role

Canadian PM made statement about Nijjar killing after being pressed by The Globe and Mail about publishing a report.

US has seen intelligence suggesting Indian agents may be involved, but doesn't want to damage relations with India.

If US has credible evidence, it's unclear why they only say India 'may' be involved.

Investigation has gone on for months with no arrests, suggesting culprits may have already fled Canada.

The longer the investigation drags on, the less likely police will be able to identify the killers.
