Imagine being stabbed 5 times lying on the floor dying then see the police arrive and think they’ve come to save me BUT instead they hand cuff you for nothing laugh at you and drag you across the floor. There is NOT enough out cry over this.
They had arrested him, they handcuffed him, he died in Police custody.
That point is so very important.
At that point they had a legally binding duty of care to him, to ensure his welfare and safety.
They failed in that duty of care, intentionally by the looks of it.
They need to be arrested, and charges of neglect and dereliction of duty need to be commenced.
They also need to be dismissed for gross misconduct.
