Officials in San Jose, California, approved new gun control measures on Tuesday, mandating the videotaping of gun sales and requiring firearm owners to have liability insurance, just three weeks after nine people were killed in a mass shooting in the city.

City councilors unanimously approved the new measures outlined last week by San Jose Mayor Sam Liccardo. The mayor stood in front of a memorial on June 8 for the victims of the VTA shooting that happened late last month, calling for immediate action to impose sweeping gun legislation in the city.
