Justin Trudeau tries to explain himself

The Liberal leadership candidate explains how he defines failure.

Finally, he explained why the long-gun registry fit his definition of a "failed" public policy. "I voted to keep the firearms registry a few months ago and if we had a vote tomorrow I would vote once again to keep the long-gun registry," Trudeau told reporters. "However, the definition of a failed public policy is the fact that the long-gun registry is no more... The fact is, because it was so deeply divisive for far too many people, it no longer exists."
