In US v. Hall, No. 09-3165, the court affirmed Defendant's convictions for robbing a bank and committing the related crimes of brandishing a firearm in relation to a crime of violence and being a felon in possession of a firearm where 1) a denial of the mistrial was harmless error because defendant's 1984 and 1992 bank robberies were admitted into evidence at trial; and 2) even if the district court's error induced defendant to testify, the error was harmless because defendant would undoubtedly have been convicted had he not testified.
As the court wrote: "Kevin Tommie Hall was convicted of robbing a bank in November 2006
and committing the related crimes of brandishing a firearm in relation to a crime of violence and being a felon in possession of a firearm. He was not a novice, having robbed at least four banks in the past and having twice been convicted of the offense. He appeals his most recent conviction on the ground that the jury was improperly told about his prior offenses."
