Sorry, but may I just interrupt? I know we have limited time, and it may be that we want to get a broader overview on COPS. One of these papers identified some problems with COPS. It states:
Descriptions of how the system is used are available, but there are no hard data that makes it possible to assess its use.
Has an analysis been done of the effectiveness of COPS in the last...? I know that COPS changed substantially a number of years ago.
