The IPCC has said they "do not underestimate the size of their task" and will work to identify any individuals that require investigation. They said:
I must stress the scope of our work is not yet clear – and we do not underestimate the size of our task.
We do not yet know how many officers or retired officers fall to be investigated for the various matters we have identified, how many are still serving or still alive.
Work will continue to identify individuals and their circumstances, and what potential offences require investigation. We can investigate both criminal and misconduct offences after an officer has retired, though retirement prevents any misconduct sanction. We are continuing to review the underlying documentation in the report and other conduct matters may come to light
