The Conservative government may be preparing to release thousands of documents that detail the controversial handling of Afghan detainees, potentially revealing the extent to which the Tories were aware of their mistreatment, the CBC reports. The issue has dogged the Conservatives since December 2009, when it sparked a parliamentary crisis after the government repeatedly refused to disclose the documents to opposition MPs. In July 2010, a committee was eventually formed to review the documents. The Conservatives had previously argued the documents couldn’t be released because of national security concerns. A source from the Foreign Affairs department told CBC News on Wednesday the government was preparing to release the documents.
