The Tenth Circuit, in a criminal sentencing case, has determined than an Oklahoma conviction for assault and battery with a dangerous weapon qualifies as a crime of violence.  The court recognized that assault and battery in Oklahoma includes only slight touching, not sufficient to constitute violent force as required to be a crime of violence.  However, the court determined that the required use of a dangerous weapon necessarily meant that the defendant was convicted of using violent force, above the slight touching required for assault and battery without a weapon. Given the similarity between a crime of violence in the criminal context and a crime of violence in the immigration context, this case may have persuasive value in the immigration context.
