I think the issue in the US is that there are so many guns per capita and the population is so anti authority that it will take generations of confiscation before you'll get a majority of personal firearms out of personal hands.
And in the meantime you've removed the right for individuals to have the opportunity to defend themselves in dangerous situations.
It's no different, both scenarios are threats to your life until the point the trigger is pulled (then it goes from threat to attempt).
