Gun control or no gun control, people need to stop shooting other people. While there is a gun-control debate and issue, it's not the issue. The issue is that there are people who don't value life, who are willing to walk into a school full of kids and murder, senselessly. That's not a matter of gun control, it's a matter of self control. Have we gone so far as a society that when someone commits mass murder we question whether people should have guns or not? I think we should address the issue of why are people still committing mass murder?
Of course there will always be evil in the world, and there will always be people that are mentally ill or just plain horrible, but they will find a way to hurt others, guns or no guns.
I live in California, I was taught that hurting others (and yes, even killing others) was wrong, but I was also taught that if someone hits me I can hit them back, I was taught to stand up for those who need someone to stand up for them. Running away from or starting fights is not something I was taught, but defending myself and the people around me was. I've had to practice this 4 times in my life, and each time all I had to do was make a stand in order to stop the confrontation or bullying that was happening. Of course I'm just a pair of hands behind a keyboard, and these are just my thoughts, but I believe there's something to be said about teaching your kids to do the right thing, which is different from teaching them to not to the wrong thing.
