When should a loaded firearm be submitted to a laboratory?

A loaded firearm should only be submitted to a laboratory for analysis if it is delivered in person. This is because of the potential safety risks associated with transporting firearms, particularly loaded ones. Handling and transferring firearms require strict adherence to safety protocols to prevent accidental discharges or other dangerous situations.

Submitting a firearm in person allows trained professionals to ensure that the firearm is properly secured and handled throughout the process. This method also provides an opportunity for proper logging, chain of custody maintenance, and evaluation of the weapon's condition before analysis. On the other hand, requesting submission at any officer's discretion, waiting for a court order, or making arrangements for submission that do not involve personal delivery compromise safety and the integrity of the evidence collected.
