What supreme court case is not directly relevant to police civil liability issues?

One Supreme Court case that is not directly relevant to police civil liability issues is Brown v. Board of Education (1954). This landmark decision addressed racial segregation in public schools and declared that "separate but equal" educational facilities were inherently unequal, thus unconstitutional. While it significantly impacted civil rights and social justice, it does not pertain to the standards or liabilities concerning police conduct or actions.
