Sort of depends on if they have a duty of care and are required to intervene medically.

I think George Floyd is a good case study for reform; Chauvin and all officers should be required to assess for medical emergencies at all times basically and take at least some level of medical action when necessary. So Chauvin should have been required to check for consciousness and then provide aid once finding Floyd to be in medical distress.

What Chauvin and fellow officers did was already in violation of policy. The problem is that they didn’t care, and having extra rules in the policy may help others but not George Floyd. If it weren’t for cameras things would’ve turned out better for those police officers.
