An LAPD officer hold a collected assault weapon during the Gun Buyback Program event in the Van Nuys area of north Los Angeles on December 26, 2012. By noon the LAPD had collected more then 420 handguns, rifles, shotguns and assault rifles. Los Angeles' no-questions-asked gun buyback event, where weapons could be exchanged for up to $200, was held five months early after the Connecticut school shooting. Critics question the effectiveness of gun buyback events, arguing that the weapons surrendered tend to be the least likely to be used in criminal activities, such as guns which are old or malfunctioning.
Gun violence will be the focus of a joint hearing at the California state capitol on Tuesday.
California lawmakers have previously looked at banning certain weapons or limiting ammunition.
But some researchers suggest that the problem of gun violence could be addressed from a public health perspective. The California Report's Health Reporter, Mina Kim, looks at this approach in the third part of a series examining gun violence and communities.
