At first glance I thought like John. They aren’t a receptive audience, and many are irritated that they are there. Would their feedback be useful and objective? But with a little creativity, we might be able to turn it into a golden opportunity. In my experience, people usually appreciate it when we show that we need and want their input. Especially in contrast to being bored. I think the key is to be very selective about the topic; and make the presentation optional, interesting and appealing. Maybe a person introduces a video that gives them information about a topic/issue; and then asks what they think should be done. If they have ideas, they can put them in a comments box. (Since they maybe called into court any minute, you can’t really have a full-blown discussion or round table.) But I’d suggest taking baby steps; maybe do this once a month or quarter and see what happens.
