India's secretive spy agency RAW faces scrutiny abroad as its power grows at home

Indian intelligence agency RAW has long infiltrated other countries like Pakistan, but now faces scrutiny after Canada accused it of a killing.

RAW expanded reach in the West after the 2008 Mumbai attacks, using more human intelligence assets.

RAW's power has grown under PM Modi, who bolstered India's defense capabilities.

RAW operates with little oversight given no parliamentary or constitutional backing.

Greater Western cooperation with India brings closer understanding of Delhi's security concerns.
