Whether the indictment adequately alleged federal jurisdiction over the place where the homicide occurred.
Holding
The Court did not decide the indictment's sufficiency because the erroneous self-defense instruction independently required reversal.
Reasoning
Brown argued that the indictment was defective because it did not allege that the United States acquired the site for a fort, magazine, arsenal, dockyard, or other needful building, as the governing statute and constitutional provision might require. Although the indictment did allege acquisition from Texas for the United States' exclusive public use and exclusive federal jurisdiction, the Court found it unnecessary to resolve that issue after concluding that the trial instructions required reversal.
