McNabb v. United States

Background

A federal revenue officer was shot and killed near the McNabb family cemetery. Federal agents arrested several McNabb men at night. Three relatives—Freeman, Raymond, and Benjamin—were held in a bare cell, not taken before a judicial officer, and questioned repeatedly without lawyers or visits from relatives. One man voluntarily surrendered and was briefly stripped to be examined; the admissions by the three formed the Government’s case while two others were acquitted.

Reasoning

The Court asked whether those admissions could properly be used at trial. Relying on its supervisory authority over federal criminal trials and on statutes requiring prompt presentation to a judicial officer, the Court held that arresting officers who detain and subject suspects to prolonged, incommunicado questioning over two days have overstepped their duties. Because the officers failed to take the arrested men promptly before a committing authority, the Court found the statements inadmissible and reversed convictions that depended on them, without deciding the separate constitutional voluntariness question.

Real world impact

The decision bars using confessions in federal trials when officers detain and repeatedly question suspects without promptly bringing them to a judicial officer. It enforces the statutory duty to take arrestees before a commissioner or magistrate, affirms judges’ responsibility to exclude improperly obtained evidence, and signals courts will not be complicit in law enforcement’s disregard of procedural rules. The ruling overturned the convictions here because they rested on the excluded admissions.

Dissents or concurrances

Justice Reed dissented, arguing the statements might have been voluntary and warning that broad supervisory exclusion risks overturning convictions for procedural omissions not shown to coerce confessions.
