Richard Colvin is a Canadian foreign service officer who gained public attention as a witness in the Canadian Afghan detainee issue. He appeared before the Special Committee on the Canadian Mission in Afghanistan in late 2009 where he discussed a signed affidavit alleging that Afghan detainees turned over to Afghanistan prisons by Canadian soldiers were tortured. The events surrounding this issue, and the Conservative government's response to his testimony, were, according to many opposition politicians, closely related to the widespread anti-prorogation protests.
