I agree that they don't have to disclose whatever evidence they have collected, but the autopsy report is also provided to the family, hence his defence would be entitled to have it. The autopsy report is an impartial examination/assessment/conclusion. It is not just for QPS. Hawkins may be able to confirm this?
Yes, you're right - and sorry, I didn't read your post properly. All parties had the autopsy report and it wasn't reported to reveal anything sinister.
