Interesting thread in that it highlights the two perspectives at odds:
1) Gun laws are needed/not needed to reduce crime.
2) Guns are effective tools that every citizen has a right to keep and bear for protection against tyranny and attack.
In the US the first priority is our Bill of Rights (or should be, but is being eroded in the minds of citizens). The first purpose of the Second Amendment is to have arms to resist tyranny, whether successful or not.
The second purpose of the 2A is to guarantee every citizen has access to the best means to protect themselves from criminal attack: car jacking, home break-in, mugging, robbery, rape, angry drunk, etc. That implies having a gun at home or wherever you are otherwise.
To many gun owners this is the crux of the issue. We have a God given right to protect ourselves from oppressive government as well as personal attack, and a firearm is a great equalizer: woman against man, one against many, smaller against bigger.
Gun banners ignore or ridicule the right enumerated in the 2A, and even the responsibility one has to protect themselves, and favor perceived public safety over individual liberty or safety. Primary tactics of oppressive regimes to control their populace, such as gun control, propaganda, and surveillance of citizens, should not be implemented by nations that honor liberty and personal responsibility.
Taken to extremes the tactics of tyrants can be effective to control the populace and perhaps even reduce public crime, but the individual citizen gives up much liberty in exchange. A society that treasures freedom ought to recognize that freedom incurs the risk that some people will choose to abuse that freedom and hurt others. But the freedom of all is more important than the safety of some.
Even under strict regimes like China, an individual is not safe from attack. Only if the State chooses to protect them. If you live in a backwater village the government may do nothing to protect you but be quick to pounce on you for small infractions. So safety may be an illusion even after giving up individual rights. Makes it easier for the government to rule, and safer for the government police though!
As a practical
"The ultimate authority ... resides in the people alone. ... The advantage of being armed, which the Americans possess over the people of almost every other nation ... forms a barrier against the enterprises of ambition."
