"Does anyone know if there are records anywhere of how many students have died as part of civilian and military survival training in the past, say, 20 years? Maybe broken down by school, season and cause of death?"
Try this one: "Boot Camp for Kids: Torturing Teens for Fun & Profit" at
http://www.nospank.net/boot.htm It has 179 incidents, and that's probably just the tip of a bloody iceberg.
One camp had 16 deaths!
