Richard Colvin’s affidavit is unsealed.

A former Canadian diplomat warned the federal government in May 2006 of “serious” and “alarming” problems with the handling of Afghan prisoners in Kandahar. Richard Colvin, now deputy head of intelligence at the Canadian embassy in Washington, filed several reports throughout his roughly 18 months in Afghanistan…

The Conservative government repeatedly said in the spring of 2007 that it had received no credible reports of prisoner abuse. But Colvin said he warned the deputy commander of the provincial reconstruction base after he became aware of problems upon arriving in Kandahar in April 2006.
