International counter-terrorism experts have considered whether police should have let distraught relatives back into the mosques in the aftermath of the 2019 Christchurch terror attack.
Two experts, from the United States and the United Kingdom, gave evidence via audio-visual link to the inquest into the murders of 51 worshippers at Al Noor Mosque and Linwood Islamic Centre.
Frank Straub and Scott Wilson co-authored a report about the terror attack, and were asked to critically examine the emergency response.
Anna Sargent was in court.
