Yesterday the Fourth Circuit handed down an interesting Fourth Amendment decision in United States v. Robertson, involving a consent search at a bus shelter. It’s a rare published decision from the Fourth Circuit, with a divided vote, and my tentative view is that the dissent is correct.
As I understand the facts, several officers converged on the bus shelter (which I assume something like this) to try to figure out if any of the people at the shelter knew of a foot chase involving a gun that had just been reported in the area. Robertson was one of the men sitting at the bus shelter, and he was approached by Officer Welch. Welch asked Robinson, “Do you have anything illegal on you?”, but Robertson remained silent. Welch then waved Robertson toward him and said, “Do you mind if I search you?” Robertson stood up, walked two yards towards Officer Welch, turned around, and raised his hands above his head. Welch interpreted that as consent, and conducted a search. The search recovered a firearm, and that led to charges for illegal firearms possession.
