The problem of course is that the police, who have been shown already to have lied, may just lie to that as well. Though unlike the derisory penalties for lying to the IPCA, lying to the Coroner is actually perjury, punishable by 7 year's jail.
But I think this is part of a bigger problem: a culture of reflexive dishonesty among police. They lie to the IPCA, they lie to the public, they lie to Parliament, to protect themselves and their "reputation", seeming to think public trust can be maintained by deceit. It has the opposite effect. And yet, they keep doing it. So maybe its time for another inquiry into police culture, aimed at stamping out this culture of dishonesty, so we can have a police force capable of performing its basic functions with integrity, rather than what seems to be little more than a gang with better uniforms.
