The government has said sorry for the Christchurch terror attack, after the release of the 800-page report from the Royal Commission. The report noted NZ had under-resourced security agencies, a patchy system for information sharing and enforcement, lax practices for firearms licensing and too much of a focus on the threat of Islamic extremism. Despite these findings, the report says nothing could have been done to stop the attacks, which left 51 Muslims dead, and the agencies were not to blame. Police Commissioner Andrew Coster speaks to Susie Ferguson.
