In the case of the rafting accident, there needs to be a good investigation on the owner of the boat. He took it upon himself to guide this young group (all of them in their early 20s) and should have known about the damn. If this man knew this danger exsisted and still ran this at night then charges need to be filed. Accidents are one thing, but negligence is totally different. Most people know the risks in normal conditions, but this was totally avoidable. Guiding during the day is one thing, but rafting in the dark is just plain stupid. People need to be accountable.
