Michigan Department of State Police v. Sitz
For police officers, Michigan Department of State Police v. Sitz means that DUI checkpoints are not automatically unconstitutional just because officers lack individualized suspicion for each driver stopped. A checkpoint may be lawful if it is structured, limited, and aimed at roadway safety rather than general crime control.
Brady v. Maryland
Brady v. Maryland requires prosecutors to disclose material evidence favorable to the accused when it bears on guilt or punishment. The rule protects the fairness of criminal trials and applies regardless of whether the prosecution acted in good or bad faith.
Pearson v. Callahan
Pearson v. Callahan changed qualified immunity procedure. The Court held that judges are no longer required to decide the constitutional violation question before asking whether the law was clearly established.

Miranda Interrogation
For federal officers, and for state or local officers working closely with federal agents, Corley v. United States is a reminder that Miranda warnings are not the only timing concern during interrogation. Advising a suspect of rights and obtaining a waiver are important, but they do not automatically solve a prompt-presentment problem.
Use Of Force
Mullenix v. Luna is important for officers because it shows how qualified immunity works in use-of-force cases, especially vehicle pursuit cases. The decision does not say that officers may freely shoot at fleeing vehicles.
