"Perhaps, but the root causes of violence should be addressed instead of embracing a solution that potentially leads to more violence."
Campus liberals. *sigh* Let's assume for a moment that we even know and can agree, as a society and political body, as to the exact causes of violent crime. Let's further assume that we are right. How long will it take to fix it? Assuming the "fix" could be immediately implemented, it would be at least one generation (generally accepted for current Americans as 25 years) to "breed" a generation free of violent crime. It would take an additional 5-10 years to wait for those currently so inclined to reach an age where their violent crime tendencies tend to drop significantly. So in a best case scenario the numbnuts writing this would be near retirement age before such an effect would be substantially effective even given best case assumptions.
"Yet you know, all the while, that the person next to you could be carrying a legal, concealed firearm. Do you feel safe?"
The misguided minds. How about, "Yet you know, all the while, that the person next to you could be carrying an illegal, concealed firearm and it will be a minimum of 2 minutes before help will arrive if he starts to kill people. Do you feel safe?" Oh snap! Reality interfering with simplistic, short-sighted, unrealistic liberal horse squeeze.
