(f)

1. (1) Any firearm, ammunition which may be used with the firearm, or any deadly or dangerous weapon which is owned or possessed by a member of a criminal street gang for the purpose of the commission of any of the offenses listed in subdivision (e) of Section 186.22, or the commission of any burglary or rape, may be confiscated by any law enforcement agency or peace officer.
2. (2) In those cases where a law enforcement agency believes that the return of the firearm, ammunition, or deadly weapon confiscated pursuant to this subdivision, is or will be used in criminal street gang activity or that the return of the item would be likely to result in endangering the safety of others, the law enforcement agency shall initiate a petition in the superior court to determine if the item confiscated should be returned or declared a nuisance.
3. (3) No firearm, ammunition, or deadly weapon shall be sold or destroyed unless reasonable notice is given to its lawful owner if his or her identity and address can be reasonably ascertained. The law enforcement agency shall inform the lawful owner, at that person’s last known address by registered mail, that he or she has 30 days from the date of receipt of the notice to respond to the court clerk to confirm his or her desire for a hearing and that the failure to respond shall result in a default order forfeiting the confiscated firearm, ammunition, or deadly weapon as a nuisance.
4. (4) If the person requests a hearing, the court clerk shall set a hearing no later than 30 days from receipt of that request. The court clerk shall notify the person, the law enforcement agency involved, and the district attorney of the date, time, and place of the hearing.
5. (5) At the hearing, the burden of proof is upon the law enforcement agency or peace officer to show by a preponderance of the evidence that the seized item is or will be used in criminal street gang activity or that return of the item would be likely to result in endangering the safety of others. All returns of firearms shall be subject to Chapter 2 (commencing with Section 33850) of Division 11 of Title 4 of Part 6.
6. (6) If the person does not request a hearing within 30 days of the notice or the lawful owner cannot be ascertained, the law enforcement agency may file a petition that the confiscated firearm, ammunition, or deadly weapon be declared a nuisance. If the items are declared to be a nuisance, the law enforcement agency shall dispose of the items as provided in Sections 18000 and 18005.
