Yes. In the U.S. we've tended to view volunteers as doing very low-level type tasks, what I generally say in addressing the issue with American police forces. Typically we see volunteers being brought together when there's a community festival and we need somebody to sit on a barricade to block traffic from going down a particular road. It's not a particularly high-skill task but an important task. We tend to view volunteers as supporting fairly low-level security and public order tasks, supporting very low-level clerical tasks.
I've heard of examples of agencies in the U.S. in the last couple of years training civilian volunteers to gather forensic evidence at crime scenes, again, using that as a way to dedicate fully trained staff for more serious incidents. You have burglary incidents where the forensics tend to be fairly simple: photographing a crime scene, dusting for prints perhaps, collecting some type of tool-mark impression, things of this nature. Having a civilian do these types of low priority, less serious types of events that tend to be quite high in volume and consume a lot of resources allows for fully trained personnel to focus on more complex violent crime incidents.
I'm not sure to what extent that situation has been legally vetted in terms of admissibility of evidence in U.S. courts. It goes back to cost and value for us and whether we are willing to offset for the savings in cost.
