The document discusses the complex legal issues involved in personal injury cases related to swimming pool accidents. It notes that proving causation can be difficult, as memories are unclear and multiple factors may have contributed to an injury. A clear case of liability involves an unguarded, unmonitored pool where a swimmer suffers a heart attack and drowns. However, most cases do not present clear liability due to disputes over facts and challenges proving causation. The document provides guidance for attorneys to carefully evaluate statutes, case law, causation, credibility and other factors before taking on a pool injury case.
