"The wrong hands"
Just whose hands are "wrong"? And who is this "we" who'll be doing the "keep away"? Government employees? I laugh at the absurdity of that suggestion.
I suppose "the wrong hands" are those who want to hurt you. If that's the case, cops and other government employees have the "wrongest" hands of all, along with the thuggish members of freelance gangs. Don't make a distinction where none exists.
There is no possible way- NONE- to keep guns out of "the wrong hands" without also keeping them out of a lot of the right hands. Even the "minor" layers of difficulties that any good person could easily pass through tend to dissuade a lot of people from going to the trouble to own or to carry a gun. It adds expense to the cost of a gun, either in dollars or in time. Since dollars are nothing but a placeholder for time you traded to someone else, there is no difference. A lot of good people also don't like being treated like a criminal by a gang of demonstrable criminals- and then told by the brainless criminal drones with FBI computers whether or not they are "worthy" of defensive tools. It is incredibly insulting.
And bad people will never be inconvenienced in the slightest. They'll buy or steal what they want- whichever is easiest.
I would prefer to live in a society where guns are freely and openly available, with absolutely zero restrictions on anyone, so that more good people will not feel like criminals for owning and carrying weapons. Good people outnumber the truly bad ones. Any additional liberty will empower the good more than the bad (who already do whatever they feel like anyway).
So, if you are truly a pro-liberty person, stop giving any attention to the absurd "wrong hands" nonsense. It makes you look like an anti-liberty bigot.
