I'd refer to what's happening in British Columbia. They have taken a pretty careful look at their justice system. There have been a number of reports, including those of Mr. Cowper, and the government has developed an action plan on that basis.
One of the things they are looking at is the integrated management of the entire court system and how that links to the police interface to ensure that all the processes and all the technologies are as efficient and streamlined as possible. Often when you have these silos, you create procedures that are not efficient.
One of the very simple things they look at is things like scheduling of officers to make court appearances, and ensuring those schedules are done in such a way that they meet court needs while also meeting the officers' needs, in particular scheduling them, not through overtime but when he or she is on a regular shift, and asking them to come in when they know they are not likely to be as busy.
Perhaps more fundamentally, particularly for minor matters, use technology, use video conferences, have them potentially in their car or in the station providing testimony. This can't always be done in more serious cases, but a lot of the matters they deal with are fairly minor, and having them sit in a courtroom is not a good use of their time in many cases.
