Runde says:"And we're going to give people like that permits to carry? That's not gonna happen, and I won't give 'em to those people. Just because they didn't get convicted 'cause their wives wouldn't testify, doesn't give them a right to carry a gun that they may end up using in a domestic violence situation."
He's more than just confused - Sheriff Runde is not well versed in Iowa law. If he has reason to believe that domestic abuse has occurred, he is bound by a "shall arrest" statute:
236.12 Prevention of further abuse--notification of rights--arrest--liability.
1. If a peace officer has reason to believe that domestic abuse has occurred, the officer shall use all reasonable means to prevent further abuse...
2.
a. A peace officer may, with or without a warrant, arrest a person under section 708.2A, subsection 2, paragraph "a", if, upon investigation, including a reasonable inquiry of the alleged victim and other witnesses, if any, the officer has probable cause to believe that a domestic abuse assault has been committed which did not result in any injury to the alleged victim.
b. Except as otherwise provided in subsection 3, a peace officer shall, with or without a warrant, arrest a person under section 708.2A, subsection 2, paragraph "b", if, upon investigation, including a reasonable inquiry of the alleged victim and other witnesses, if any, the officer has probable cause to believe that a domestic abuse assault has been committed which resulted in the alleged victim's suffering a bodily injury.
c. Except as otherwise provided in subsection 3, a peace officer shall, with or without a warrant, arrest a person under section 708.2A, subsection 2, paragraph "c", if, upon investigation, including a reasonable inquiry of the alleged victim and other witnesses, if any, the officer has probable cause to believe that a domestic abuse assault has been committed with the intent to inflict a serious injury.
d. Except as otherwise provided in subsection 3, a peace officer shall, with or without a warrant, arrest a person under section 708.2A, subsection 2, paragraph "c", if, upon investigation, including a reasonable inquiry of the alleged victim and other witnesses, if any, the officer has probable cause to believe that a domestic abuse assault has been committed and that the alleged abuser used or displayed a dangerous weapon in connection with the assault.
3. As described in subsection 2, paragraph "b", "c", or "d", the peace officer shall arrest the person whom the peace officer believes to be the primary physical aggressor. The duty of the officer to arrest extends only to those persons involved who are believed to have committed an assault. Persons acting with justification, as defined in section 704.3, are not subject to mandatory arrest. In identifying the primary physical aggressor, a peace officer shall consider the need to protect victims of domestic abuse, the relative degree of injury or fear inflicted on the persons involved, and any history of domestic abuse between the persons involved. A peace officer's identification of the primary physical aggressor shall not be based on the consent of the victim to any subsequent prosecution or on the relationship of the persons involved in the incident, and shall not be based solely upon the absence of visible indications of injury or impairment.
