1:59 Unsecured guns are among the top contributors to the nation's gun violence, so a coalition of public officials and law enforcement is putting out the call to create new safety technology. Ron Hain - the sheriff of Kane County in neighboring Illinois - said of the tens of millions of gun-owning households in the U.S, fewer than half store their guns securely. Startups in recent years have brought some potentially promising products to market - such as different kinds of personalized locks. Hain said these are being tested by law enforcement officers and firearms experts. "We have to make guns childproof, and as accident-proof as possible," said Hain. "In an age of technological innovation, this is not an unsolvable problem."
