The Christchurch massacre was planned and executed by a man who appeared to slip the attention of authorities in plain sight.
The man behind the attack had a firearms licence approved within three months of his arrival in New Zealand.
His referees included a man who had been in his company for just 21 days over a decade. In less than 2 years, he amassed ten high powered rifles and guns.
In the gym, the terrorist was using steroids to bulk up his body while on the internet he barely disguised his admiration for right wing extremism.
Nobody picked him out as a threat.
The government has said sorry, noting 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.
