Whatever your personal take on gun control, it is all but certain that a killer set on killing is more likely to attack a target where the citizens are unarmed, rather than one where they are likely to encounter an armed citizen response.

The next time anyone remarks to you anything negative about guns, ask them this simple question: "Do you believe guns should be banned in schools?"

If they say YES, then blame them for the kids being killed in CT and explain the fallacy of gun-free zones to them. Put them on the defensive and make them justify their beliefs. Have them explain why over 20,000 gun laws have only affected the law-abiding and has done nothing to save lives - in fact, has done a lot to cause deaths. Ask them how many more people have to die in victim-disarmament zones because of their beliefs before enough is enough.

Quit playing the other guys' games; make them play yours.
Rules are for people who lose fights.
