It isn't just for Parliament. In terms of the public servants who may or may not decide to utilize your office, I think part of it is that they have to know how effective it is, or that maybe there's a higher rate of reprisal for coming to you as opposed to keeping it in-house. That could all be part of the education process, not just for committees or parliamentarians, but also for the people who potentially may have to utilize the office.
