It's just a matter of interpretation to the extent that the requirement is “as soon as is feasible after the commission of the act or omission”. It really does put an obligation on the designated public officer, but in terms of operational constraints, clearly if they're in the middle of an undercover investigation they're not going to trot out with their notebook and make a report. However, barring, I would think, extenuating circumstances as the result of operations, the obligation is in the legislation.
