Gun laws certainly can make people more safe. Look at Canada, a country with significant gun ownership. A Canadian has to jump through quite a bit more hoops than an American to own a gun. The process takes a considerable more time in Canada, ensuring fewer people who shouldn't own a gun can't own a gun. However, many law abiding citizens who pose no threat to their fellow citizens are approved for gun ownership. People with mental health issues, drug issues and domestic violence histories are much more likely to not be able to buy a gun.
