Stripped of his ability to prescribe narcotics by the Arkansas State Medical Board, doctor places grenade near then-chairman of the board’s vehicle. The explosion seriously injures the then-chairman. By chance, city workers find 98 grenades buried near the doc’s home. Police find 76 machine guns in the doc’s home. Gov’t tries to forfeit the guns. District court denies forfeiture but orders the guns sold at auction because the doctor, now a convicted felon, cannot lawfully possess them. Eighth Circuit: Affirmed. Proceeds from the auction go to the former chairman.
