ARS 13-2904 is the disorderly conduct section and reads:
13-2904. Disorderly conduct; classification
A. A person commits disorderly conduct if, with intent to disturb the peace or quiet of a neighborhood, family or person, or with knowledge of doing so, such person:
1. Engages in fighting, violent or seriously disruptive behavior; or
2. Makes unreasonable noise; or
3. Uses abusive or offensive language or gestures to any person present in a manner likely to provoke immediate physical retaliation by such person; or
4. Makes any protracted commotion, utterance or display with the intent to prevent the transaction of the business of a lawful meeting, gathering or procession; or
5. Refuses to obey a lawful order to disperse issued to maintain public safety in dangerous proximity to a fire, a hazard or any other emergency; or
6. Recklessly handles, displays or discharges a deadly weapon or dangerous instrument.
B. Disorderly conduct under subsection A, paragraph 6 is a class 6 felony. Disorderly conduct under subsection A, paragraph 1, 2, 3, 4 or 5 is a class 1 misdemeanor.
On the facts you described, I don't see how the prosecutor could prove "intent to disturb the peace or quiet" of any neighborhood or even the spouse. This was a real stretch to cite to begin with. I would be amazed if the prosecutor elected to proceed with this charge.
ARS 13-3601 is the domestic violence section. It is quite long and you can see it in its entirety at:
In the first paragraph, it incorporates the assault section (13-1203), so proving 13-3601 still requires proving an assault was committed under section 13-1203. As described in your question, this will be a tough case for the prosecutor to prove. If charges are filed, this still looks like an appropriate case for deferred prosecution.
