I don't think Time and Business Insider are anti-gun groups, even allowing you find NPR and Vox too left wing to read.
Indiana is kind of in the middle of the pack, both in the strictness of its gun laws, and its gun death rate (14 per 100,000, better than Alaska's more than 24 per 100,000, but a lot more than Hawai'i and California, at about 4.5 and 7.2 per 100,000).
Just like the addition of seatbelts to cars, guns are a part of our life that can be made safer with sensible regulation. People in all 50 states have guns -- the Constitution guarantees them the right -- but making sure that people are properly trained and guns are being properly stored and carried saves lives -- a lot of them.
California has 40 million people: at 7.2 annual gun deaths per 100,000, that's close to 3000 per year (ouch!), but if it had Alabama's laws and rate of gun deaths, it would have about 10,000 gun deaths per year (OUCH!). 7000 lives saved is GOOD.
