My hon. Friend argues for a different style of approach. He talks about a limited period and then about the need to safeguard that information following an event. I do not agree with him on that, as that is a separate debate. However, I agree that where we can see accurate data being provided, we seek to surface that as much as possible as part of the approach on transparency.
As the commissioner made clear in his report, the Home Office was working with him to improve the statistics collected by public authorities. He identified a number of further elements in his report, including the total number of applications submitted, the total number of items of data requested, the total items of data broken down by statutory purpose for which they were required and the total items of data broken down by crime type or other purpose for which they were required, which is the point that my hon. Friend has just made.
We are working with public authorities to ensure that most of these statistics are already being collected by them, and are progressing work to agree on the relevant practicalities such as agreed nomenclature that would enable those that had not already been collected to be collected. Transparency is important in ensuring continued public trust in the agencies and police forces that have been granted intrusive powers. However, transparency does have limits. We should not commit to such transparency that would publicise police and other sensitive investigative methodology, as explaining exactly how our investigators do their job will naturally lead to terrorists, criminals and others who wish us harm knowing how to avoid detection. We must also be careful not to weigh down investigators with too much bureaucracy such that they cannot perform the important function of preventing and detecting crimes and keeping us safe.
