Yep, but I hope you got my point...!
Safety or unsafety of firearms depend from the individual. Even in a total-gun-rights society like in the U.S., some people are not to be trusted with firearms (mentally ill, drug addicts, felons). Moreover, sttating that only cops are to be trusted with arms is a falsity, and such a gun policy would not prevent mass murders.
"It is criminal to teach a man not to defend himself, when he is the constant victim of brutal attacks. It is legal and lawful to own a shotgun or a rifle. We believe in obeying the law." -- Malcolm X
"We (atheists) act in good conscience because we believe in moral principles, not because we expect a reward in Heaven." -- Margherita Hack
