Nobody called an ambulance. The murderer's brother lied to the police on the phone. Their mother assisted in hiding the knife. Digwa stabbed Henry repeatedly from behind as he attempted to get away. They filmed Henry as he bled lying on the ground.
Instead of calling an ambulance and apprehending the killer, the police handuffed the bleeding victim on the ground, in spite of the fact that he had a stab wound in the face and in other areas.
"I am bleeding. I can't breathe" - "Don't think so mate"
These coppers deserve lifetime in prison at a minimum. The brother and mother are accomplices of the murder.
No forgiveness. The capital punishment is the only appropriate sentence.
