And that was my point. More fearful people are more likely to own guns, because they are afraid of themselves or members of their family/social group being victimized. More fearful people also tend to be more violent.
This is not something novel, it goes back to these kind of evolved psychological traits.
Back in the caveman days, say a lone hunter spotted a stranger from another tribe. A more fearful hunter would be more likely to engage his "fight or flight" instinct and either try to kill the foreign tribesman, or run, or hide from him. This would help ensure his survival, but, on the other hand, it would make it difficult for nearby tribes to cooperate and could easily spark a feud.
A less fearful tribesman may greet the stranger, and for his lack of fear, be killed by the stranger. Or he may help initiate a mutually beneficial alliance between his tribe and theirs.
But, more fearful people do tend to advocate violence much more, and they are probably more likely to commit violent (though not necessarily illegal) acts.
