Amnesty International is calling for accountability within the Papua New Guinea security forces.
This comes after 17 unarmed prisoners were shot and killed while trying to escape from Buimo Prison in Lae.
Amnesty has called for officers involved in the killings to be suspended and an independent inquiry held.
But the group's Pacific researcher Kate Schuetze says it is unlikely that any of those involved will even be reprimanded let alone tried for their actions.
She told Koroi Hawkns the tragic incident highlights a broader systemic issue.
