In what circumstances have undercover police agents been found to have spied on students at a state university?

In White v. Davis, supra, 13 Cal.3d 757, 120 Cal.Rptr. 94, 533 P.2d 222, the alleged surveillance activities took a more conventional form. Undercover police agents registered as students at a state university, attended university classes and meetings of campus organizations, and submitted reports to the police department for retention in individual dossiers. (Id., 13 Cal.3d at p. 762, 120 Cal.Rptr. 94, 533 P.2d 222.) This court held that the presence of the undercover police agents stripped the students and professors of the protective cloak of anonymity guaranteed by the First Amendment (id., at pp. 767-768, 120 Cal.Rptr. 94, 533 P.2d 222) ⁶ and the state privacy amendment (id., at p. 775, 120 Cal.Rptr. 94, 533 P.2d 222).
