Sisler High School here in Winnipeg runs a 1-day roleplay workshop called "In Exile - for a While" about what it's like to be a UN refugee. The students are taken to a local national park by bus, and as soon as they arrive, they are met by a truckload of men in camoflague who take them off the bus, goo through their stuff, take away their lunches and personal goods, then lead them off through the forest. They go through a variety of roleplays, including having to cross a minefield and having some of their group "separated and abducted" by militants who presumeably kill them. You can look it up on the internet as there has been a ton of media coverage about this event in recent years. I tried to organize one of these myself and was promptly told by my administrators that there was no way they would support this.
