I can only speak to my experience, and I have worked in a diversity of communities. I've worked with male and female auxiliaries, and with auxiliaries of a variety of ethnicities, including aboriginal auxiliary constables. We are constantly trying to drum up the interest in the auxiliary program. It's a significant commitment for volunteers, but that said, it's invaluable.
I can remember working at my first detachment. I was headed out the door for a call for service that related to a trespassing complaint about cows that had gone into somebody else's pasture. That was the nature of the complaint, so seemingly that's not a significant complaint to concern yourself with. The auxiliary caught me before I was going out the door and asked me if I realized that there was a decade of conflict between those two neighbours and that there had been volatile conflict that had involved assaultive behaviour.
What seemed like a really innocuous and non-threatening call very quickly became a call that three armed police officers went to, because of the level of violence that had escalated between those two neighbours. That's the value that auxiliaries provide in terms of public and police safety. I learned very quickly that the first person I sought out at the detachment was that long-standing community member who was an auxiliary and had the knowledge of where those historical conflicts were and what the history of that community was.
