Today we were shown around the firearms library and shooting range by West Grouse. The firearms library at CSULA is the 3rd largest collection of firearms in the USA and comprises both the LAPD library and the Sheriffs Department library.
Both the Sheriffs Department and the LAPD have the opportunity to collaborate together on investigations whilst also having the resources to work on multiple individual cases within their organisations due to the way the facility is set out and shared.
Firearms technicians test and inspect a number of different weapons. This is done in both a lab setting and on the firing range and even using water tanks and chambers filled with cotton padding.
Firearms testing is conducted on suspect weapons to determine if a weapon was used in a crime by matching it to evidence at the scene and to also assess potential residue found at the scene or on the firearm.
Testing is also conducted to determine if the firearm has been modified and the recovery of firearm serial numbers can also be achieved by technicians in the lab.
