In Lopez v. City of Oxnard (1989) 207 Cal.App.3d 1, the appellate court stated, "jail personnel may not be similarly situated to police officers on the street, but they, too, are entitled to rely on process and orders apparently valid on their face." The court further stated, "although a sheriff is 'obliged to use reasonable diligence to perform the duties of his office in a lawful manner,' he need not ordinarily search for facts not apparent on the face of a warrant." (Id. at p. 10.)
