Murder trial witness says Zachary Rolfe's actions on night of Kumanjayi Walker's shooting 'consistent with training'

The final witness in the murder trial of Northern Territory police officer, Zachary Rolfe, has told jurors the officer was following his training when he shot an Aboriginal man two years ago. As court reporter Melissa Mackay explains the 'use of force' expert called by the defence said he believed the scissors used to stab Constable Rolfe could have been lethal.
