I disagree. Deaths from injuries sustained during arrest and transport should not happen, with an exception being as the result of the transport vehicle being in a serious accident.
Deaths from suicide should also not happen, and certainly not with the frequency they seem to happen.
I would also argue that nor should deaths 'at the hands of others' which I take to mean at the hands of other inmates. Also should not happen.
Why not go for zero in custody deaths? Why not make that a goal?
Because zero is a logical contradiction.
In any process, defects can be reduced by dedicating more resources to the process and quality control. The law of diminishing returns appears quickly and if we reduce defects to zero, costs expand to infinity.
I think you misunderstood my post. The three causes of death I listed, are not reasonable to expect in jail, since these are three things directly under the control of jail management. Jail management must be held strictly accountable for death by these causes.
There will still be cases where a person's death maybe precipitated by the jail, but beyond the control of the jailers. An asthmatic may have a sudden attack and die before aid arrives. The attack may have been brought on by stress, but the person would have died just the same if he had been in a restaurant. There are a lot of similar medical conditions which may become a crisis under severe stress.
A county lock up is not a trauma center or an ICU. It is possible to eliminate jail death due to suicide, injuries, or violence, with reasonable expense.
To eliminate all preventable deaths would require far more resources than we have.
