Yes but restricted gun sales restricts criminals access to them. I'm not talking about people who are planning to rob a bank, they'll probably be willing to get them, I'm talking about "punks" on the edge of society. So the punk is less likely to be bothered to get a gun. But don't listen to me I'm a liberal/socialist European
(yes I am aware that countries like Australia have a high gun ownership but less deaths but I don't know anyone who has a gun, I think that most gun owners here live in the country).
