It's been almost a week since the terrible plane crash in Iran that killed 176 people, including 57 Canadians, and the emotions in this country are still raw. Bruce MacKinnon is the editorial cartoonist for the Chronicle Herald, Nova Scotia's largest newspaper. This past weekend, he channelled the anger, frustration and anguish of this tragedy with a cartoon that quickly went viral. It's not the first time MacKinnon's work has spoken to people so widely. You may remember his commemoration of Corporal Nathan Cirillo, who was killed at the National War Memorial in 2014, or his cartoon about Brett Kavanaugh's Senate hearing, which was hugely circulated in the United States last year. MacKinnon joined q's Tom Power on the line from Halifax to talk about his response to the plane crash in Iran and the fine line he has to walk when dealing with tragedies.
