If you guys were to make use of the fantastic resource that you're using to hypothesize, you may come across something useful. Such as...
No person who has been restrained pursuant to an order of any court, including an ex parte order as provided in this subsection, from contacting, threatening, or physically abusing any person, shall possess, control, or transfer ownership of any firearm or ammunition therefor, so long as the protective order, restraining order, or any extension is in effect, unless the order, for good cause shown, specifically permits the possession of a firearm and ammunition. The restraining order or order of protection shall specifically include a statement that possession, control, or transfer of ownership of a firearm or ammunition by the person named in the order is prohibited. Such person shall relinquish possession and control of any firearm and ammunition owned by that person to the police department of the appropriate county for safekeeping for the duration of the order or extension thereof. In the case of an ex parte order, the affidavit or statement under oath that forms the basis for the order shall contain a statement of the facts that support a finding that the person to be restrained owns, intends to obtain or to transfer ownership of, or possesses a firearm, and that the firearm may be used to threaten, injure, or abuse any person. The ex parte order shall be effective upon service pursuant to section 586-6. At the time of service of a restraining order involving firearms and ammunition issued by any court, the police officer may take custody of any and all firearms and ammunition in plain sight, those discovered pursuant to a consensual search, and those firearms surrendered by the person restrained. If the person restrained is the registered owner of a firearm and knows the location of the firearm, but refuses to surrender the firearm or refuses to disclose the location of the firearm, the person restrained shall be guilty of a misdemeanor. In any case, when a police officer is unable to locate the firearms and ammunition either registered under this chapter or known to the person granted protection by the court, the police officer shall apply to the court for a search warrant pursuant to chapter 803 for the limited purpose of seizing the firearm and ammunition.
For the purposes of this subsection, good cause shall not be based solely upon the consideration that the person subject to restraint pursuant to an order of any court, including an ex parte order as provided for in this subsection, is required to possess or carry firearms or ammunition during the course of the person's employment. Good cause consideration may include but not be limited to the protection and safety of the person to whom a restraining order is granted.
So, cop knocks on door. "Hi. Here, have this TRO."
If she sees any guns or ammo, she can take them. If not, the conversation continues:
"So, I have this list of guns that are registered to you. Can I have them all, please? Oh, and any ammo?"
You say "No, no, that's not gonna happen."
Cop shrugs. "Shoots. You have just committed a misdemeanor. Expect a fine for that. I'll be back with a search warrant. See you soon!"
