What happens to firearms submissions except for those discharged by a police officer?

The correct answer reflects the protocol followed regarding firearms that are submitted for analysis after being involved in an incident. When firearms are submitted, except for those that were discharged by a police officer, they are entered into the Firearm Analysis System. This process is essential for tracking and analyzing firearm-related evidence, which helps in criminal investigations and can aid in linking firearms to other cases or incidents.

By entering the firearm into the Firearm Analysis System, law enforcement agencies can utilize advanced forensic analysis techniques to gather information about the firearm’s history, including its ownership, possible usage in crimes, and ballistic properties. This systematic approach ensures that valuable evidence is preserved and can be accessed for future inquiries or prosecutions.

The other options do not align with the protocol for handling such firearms. Immediate destruction would not be appropriate since they may serve as critical pieces of evidence. Handing over to the district attorney typically occurs at a later stage of the legal process, and logging for potential retrieval implies a different handling procedure that does not necessarily involve analysis or tracking.
