Does plaintiffs' brief on litigation privilege in a non-foreclosure action need to be reviewed more closely than it needs to be?

Plaintiffs' discussion of the litigation privilege consists of little more than a summary of general abstract principles that is devoid of a single citation to the record. (See generally Metzenbaum v. Metzenbaum (1950) 96 Cal.App.2d 197, 199 ["An appellate court cannot be expected to search through a voluminous record to discover evidence on a point raised by appellant when his brief makes no reference to the pages where the evidence on the point can be found in the record"].) Although plaintiffs' brief summarizes various holdings pertaining to different aspects of the litigation privilege, it fails to adequately explain how those holdings relate to the non-foreclosure claims asserted in the complaint.
