101 California Street shooting - Wikipedia
I remember writing this law firm's partners or something like that after this shooting about getting their help with bringing practical materials for survivors/victims of crimes into libraries of all kinds and they, or whoever responded back then, wrote me that they did not have the resources to do anything about the issue I raised. I think they were thinking more broadly about curbing violence done by weapons meant for soldiers in combat situations and not with my concerns about access to meaningful information for those trying to deal with fallout of these shootings.
I do see stuff in that Act below that address these concerns though.
