Last week, Law Center Executive Director Robyn Thomas and Michael McLively, one of our staff attorneys, published an article, “Sighting the Homemade Gun Threat” in the Daily Journal. Outlining two potential gun laws, Senate Bill 199 and Senate Bill 808, which Governor Brown signed and vetoed respectively, the article discusses the dangers of homemade guns and the impending threat of 3-D printed guns as they gain popularity. Originally published in both print and online, here is the article shared in full.
Sighting the Homemade Gun Threat
Gov. Jerry Brown made headlines last week by signing Assembly Bill 1014, a bill that will establish an innovative “Gun Violence Restraining Order” procedure in California. On the same day, two lesser-known bills, Senate Bill 199 and Senate Bill 808, were signed and vetoed by the governor, respectively, without generating much notice. Despite their relatively low profile, these bills deserve our attention as they provide interesting insights into some of the critical gun issues we’ll be facing in California looking forward.
The Serious Danger of Homemade Guns
Last Tuesday, Brown vetoed SB 808, which was an initial attempt to regulate the serious threat posed by homemade firearms. The bill would have required all such guns to be registered with the California Department of Justice and given a serial number.
This would have been a small step in the right direction by giving state authorities a better idea of just how many homemade guns are out there, but much more needs to be done in order to effectively nip this growing menace in the bud. Brown’s veto of this bill provides an opportunity to revisit this issue afresh and to reconsider the best way to properly address this problem in 2015, before it is too late.
Homemade firearms come from two main sources: the assembly of what are known as “partial receivers,” and 3D printing. Each presents its own set of unique problems and concerns.
A partial receiver is a partially finished metal component that holds the basic mechanisms that allow a gun to operate. Partial receivers are not regulated federally or at the state level. They can be purchased without a background check and turned into a fully functioning firearm with a relatively cheap and simple mechanical process that takes only one to seven hours to complete.
Partial receivers provide a way for mass-murderers and other criminals to skirt California’s otherwise strong gun laws, including mandatory background checks and the state’s prohibition on assault weapons. Using a partial receiver allows a person to build a functional assault rifle in a matter of hours. A recent and devastating shooting in Santa Monica highlights this danger all too well. John Zawahri failed a gun-purchase background check before deciding to buy an unfinished receiver and assembling his own assault rifle, which he then used in a terrible attack that left five dead, including Zawahri.
