In Rogers v. Jones (1976) 56 Cal. App. 3d 346, 128 Cal. Rptr. 404, the court refused to impose a duty on a football stadium parking lot operator to prevent an attack by one fan upon another. The court held that the measures needed to prevent such an incident would be unreasonably burdensome, necessitating that one guard be provided for every fan. It concluded that the harm to the plaintiff was not sufficiently foreseeable to warrant such a heavy burden. (Id. at p. 352.)
