¶1Mr. Roger N. Boyd, Washington, D. C., with whom Mr. Eldon H. Crowell, Washington, D. C. (both appointed by this court) was on the brief, for appellant.
¶2Miss Carol Garfiel, Asst. U. S, Atty., with whom Messrs. David C. Acheson, U. S. Atty., Frank Q. Nebeker and John E. Hogan, Asst. U. S. Attys., were on the brief, for appellee.
¶3Before Bazelon, Chief Judge, and Washington and Bastían, Circuit Judges.
¶5Appellant admitted his presence at the scene of the robbery for which he stands convicted. He offered a plausible explanation of his apparent complicity. But the jury found him guilty upon sufficient evidence after an exemplary charge on reasonable doubt.1 Although we affirm the conviction, two issues deserve comment.
¶6Appellant contends that a question that the court asked him during his explanation of the circumstances of his arrest prejudiced his defense, by implying to the jury that the judge did not believe an important element of appellant’s story.2 Whether the jury would have so understood the question is highly doubtful. And no objection was made. The question was a small incident in -an otherwise sound trial. We do not regard it as plain error, Rule 52(b), Fed.R. Crim.P.
¶7Appellant also complains about the court’s delivery of the so-called Allen charge. After seven hours, the jury reported itself in “hopeless deadlock” and the judge called it back to the courtroom to deliver that charge.3 The jury returned its verdict in a little over thirty minutes. We do not agree with appellant that the judge must have known that the jury was unevenly divided and therefore should have refrained from delivering the charge. However, since the charge is potentially coercive, its content and manner of use deserve scrutiny.4 Here the trial judge adhered precisely to the summary of the approved charge given by the Supreme Court in Allen.5He in-*99troducéd the charge with only a reminder of the time already spent trying the case and of the Supreme Court’s approval of the charge. There was no objection. In these circumstances, we do not think the impact of the introduction rendered the charge, as a whole, error.
¶8Affirmed.
¶9BASTIAN, Circuit Judge, concurs in the result.
