sentences:  In August 2011, a party of teenagers in Norway was attacked at night by a polar bear leading to the death of a seventeen-year-old boy and injuries to several others.Both the Norwegian authorities and a private enquiry commissioned by BSES and chaired by a UK high court judge criticized the expedition's defective gun, and inadequate warning arrangements, the judge ruling that the accident was preventable.However, in July 2014, a coroner cleared the BSES of neglect as failure "was not total or complete."
