Actually, a mixture of one and 2. There are way too many dangerous (accident prone) gun owners out there that think they are experts. The problem is, we can't easily identify them. So we train everyone like the Swiss does. No training no guns. Once the training is completed, remove the restrictions for the most part. It's already been proven those that go through the training (as in CCW) are the absolute least likely to misuse their weapons either for criminal activity or just plain stupidity. Yes, there are a couple of times reported but, almost always, the 16 hour, including the gun range, seems to get rid of the unsafe one. If you don't pass, you don't get to have a gun. Most will pass. We have unlicensed Open Carry here. Most of these morons running around with their guns on their hips all think they are the second coming of Wyatt Earp. These people don't prevent criminals. All I see, in a pinch, is a Criminal shoot them and getting a brand new fresh gun out of the deal. The CCW folks are a different breed.
