Hkucharek, Do you have or know of such any existing leaflet that might be translated into Luganda?

I'd have to agree with Tomash on the idea of having an club membership with a card or similar. Previously I've been an city ambassador for Couchsurfing.com and they created a web page that helped generate business cards for members to distribute as needed. http://www.couchsurfing.org/business_cards.html What Tomash and others suggest I think is a wise suggestion because it lends credence to people in the field while also providing some minor advertising.

In my particular case, the police guards involved would likely have not detained me so long if they had been given a business card. Obviously it would be more legitimate if they could reference what is seen on the card with a website listing of official members. Obviously this isn't exactly possible as 200,000 users is hard to list, and there are privacy concern, however given the continuing issues that OSM volunteers have seen http://thinkwhere.wordpress.com/2010/01/04/a-tale-of-a-mapper-from-uganda/ it might be worth organizing some sort of semi-formal guidelines, tracking, and response mechanism for users. Perhaps not globally, but focused on countries and areas where incidents are known to take place. I'll list this on the forum, but I'm curious what people think?
