There are provisions now in the legislation that permit the delay of inclusion in a report until a time when that would not compromise an ongoing investigation, compromise the identity of an undercover officer, or endanger someone's life or safety. Those all seem to be quite reasonable reasons to delay, although we have proposed that there should be some independent scrutiny on whether those factors do exist. So simply delaying the provision of the information to the wider public would probably continue to protect the interests you're concerned about. There seems to be no reason that the information should not be collected and analyzed.
If it's being delayed, once again I would raise our favourite solution to these problems: an audit body that could look at the information before it was public and scrutinize it. Then to whatever extent it was being delayed, the audit body would give us some comfort that nevertheless it was being looked at carefully by someone with the responsibility to do so.
