Dean Brothers Corp. owns and operates a steel drum manufacturing plant. Lowell Wyden, the plant superintendent, hired Best Security Patrol, Inc. (BSP), a security company, to guard Dean's property and "deter thieves and vandals." Some BSP security guards, as Wyden knew, carried firearms.
Pete Sidell, a BSP security guard, was not certified as an armed guard but nevertheless brought his gun, in a briefcase, to work.
While working at the Dean plant on October 31, 2010, Sidell ?red his gun at Tyrone Gaines, a manufacturing plant employee, in the belief that Gaines was an intruder. The bullet struck and killed Gaines. Gaines's mother has ?led a lawsuit claiming that her son's death was the result of BSP's negligence, for which Dean was responsible.

2. What is Dean's best defense? Explain.
