Can a federal district court impose a sentence of life imprisonment on a defendant who has pleaded guilty to a charge of aggravated assault?

On this record, we cannot honestly say that the district court's imposition of a sentence of life imprisonment was "illogical, implausible, or without support in inferences that may be drawn from facts in the record." Martinez-Lopez , 864 F.3d at 1043 (citation omitted). In other words, no error occurred and without error there can be no plain error. See Puckett v. United States , 556 U.S. 129, 135, 129 S.Ct. 1423, 173 L.Ed.2d 266 (2009) (explaining that "there must be an error" before plain error review is invoked).
