On 19 April 2010, MacKenzie was interviewed on CTV's "Power Play" in relation to accusations by Ahmadshah Malgarai, a translator, who witnessed interrogations in which a witness allegedly recounted that the Canadian military murdered a 17-year-old Afghan. MacKenzie dismissed those accusations as "crap" and "insulting" to the Canadian military, while he viewed the denial by the Canadian military as credible. Amir Attaran, a law professor and lawyer for Malgarai disagreed with Mackenzie, arguing that instead of comparing credibility, the military must release the records of detainee interrogations to Parliament, so that Parliament may determine what occurred, based upon the available facts. According to Attaran, it is a legal requirement that the documents regarding detainee interrogations be produced, while they need not be made public. MacKenzie called it "ridiculous" and "ludicrous" to table such documents in Parliament and that, furthermore, he was "not concerned" about the legal requirement to do so. Near the end of the interview, MacKenzie verbally attacked Dr. Attaran: "Last time I checked, in various polls being done across Canada, the Canadian Forces are at the very top of trustworthiness with the Canadian population. I won't mention where lawyers were slated."
