Some Fourth Amendment decisions made by the U.S. Supreme Court are “narrow” in that they are limited to a very particular set of facts under particular circumstances. Other decisions by the court can be broad and have an impact on law enforcement actions in many different situations. Like a large rock thrown into a deep pond, these broad decisions create ripples that travel far from the center and have an effect on other law enforcement actions not contemplated by the original decision. Rodriguez v. United States is one such decision.
