Quake engineering boss Peter Smith on CTV decision

Queen's Counsel Nigel Hampton, who represented some of the families of those who died in the CTV building, believes the decision not to prosecute the building's engineers was not warranted, and that a prosecution could have succeeded under the existing law. Documents show police abandoned a prosecution even though engineers told them it was clear that substandard design caused it. President of the Society for Earthquake Engineering Peter Smith joins us with his reaction to the decision.
