The ostensible purpose of the “safe storage” laws is to keep guns out of the wrong hands. In reality, the requirement to keep weapons locked up and separate from ammunition contributes to criminal acquisition of arms. A gun owner whose weapons are inaccessible for immediate defensive use as mandated by law is easy prey to thugs able to barge in and force him to unlock the safe. Voluntary use of safes reduces the incidence of gun theft from unoccupied dwellings even as criminals switch to crimes of stealth for fear of getting shot by the law-abiding.
Similarly, the ostensible purpose of reducing the number of weapons in private hands is crime reduction. It has the opposite effect in reality. In a society where most adults are armed, having a weapon gives little advantage to the thug. In a disarmed society, being armed gives an overwhelming advantage, making acquisition of arms a much higher priority. Moreover, peaceable people unfamiliar with firearms greatly overestimate their effectiveness, making them more likely to surrender and be raped and/or executed rather than fight on even terms and likely win.
Registration of firearms, in theory, is to make solving crimes easier. It also criminalizes such acts as friends accidentally mixing up two identical firearms at the range and each person taking the wrong one home. How does criminalizing an action which harms no one make any sense, unless there’s an ulterior motive to the registration?
