A patron sues a guard under 42 U.S.C. §1983 (federal civil rights statute) alleging a Fourth Amendment violation. The threshold issue for most private-security cases is:
Explanation
§1983 reaches only persons acting 'under color of state law' (state actors). Purely private security guards generally do not meet that test (Lugar v. Edmondson Oil Co., 457 U.S. 922 (1982)). Exceptions exist: a guard cross-deputized as a peace officer, a private guard acting in concert with police (joint action), or one performing a 'public function' traditionally reserved to the state. Without state action, §1983 fails — but plaintiffs can pursue state tort claims (false imprisonment, battery) and California's Bane Act (Civil Code §52.1), which reaches private actors. On-duty status (a), uniform (b), and citizenship (c) are not the threshold issue.
