A federal judge in San Diego has upheld a California law allowing personal information of gun owners to be shared with researchers. The judge ruled against a lawsuit from a group of gun owners trying to block the new state law that allows their info to be shared with researchers at UC Davis and Stanford studying gun violence. The gun owners had argued that Assembly Bill 173 violated their Second Amendment rights and deterred others from buying guns and ammunition, especially in light of the incident from June of last year that saw California accidentally release the personal information of two hundred thousand gun owners online. The judge gave the group until February 10th to appeal.
