Town of Castle Rock v. Gonzales (2005) was a Supreme Court case that ruled a person does not have a constitutional right to police enforcement of a restraining order, even if the order is violated, because Colorado law did not create a mandatory entitlement to enforcement, meaning there was no "property interest" protected by the Due Process Clause. The case stemmed from Jessica Gonzales's estranged husband abducting and murdering their three children, despite her repeated pleas for police to enforce a restraining order. The Court's 7-2 decision held that the police's failure to act did not violate her constitutional rights, as the restraining order was not a guarantee of police protection.
