Sensible. Suspend them while the incident is investigated.
If, knowing departmental procedures, the examiner is saying it is homicide, and this isn't a politically-motivated judgement, then by all means throw the book at them.
But if they acted in accordance with procedures, then indict the person who wrote them, if anyone.
If there's an outcry about the officers on scene and they followed procedure, so be it. That's the time a police chief has to lead by standing up to popular opinion. You can't do policing in hindsight.
I don't know if the police normally use hoods of that type with people who are acting erratically and they have a history of violence. It's a peculiar thing to come up with on the spot. Use of a hood certainly looks like something that might cause asphyxia. So I am surprised if it is policy.
