Do you have a very long list of places where the law-abiding should be at the mercy of armed criminals? I just pointed out that I would have been the only target available to a bad guy in the waiting area of a police station. Why should I be denied the right to defend myself from such a criminal? Why do you presume that disarming me, given that I will not wilfully disobey the law, will have any effect whatever on criminal behavior?
What PR value would there be in having me defenseless and gunned down in the waiting area of a police station? You might look on it as a PR victory that a police officer was not killed, but my family would view it as a tragedy enabled by feel-good laws.
You're not at the mercy of armed criminals. You're surrounded by cops who have guns.
