My heart and prayers goes out to the victim's families. No parent should have to endure such pain.

The shooting today in Newtown, CT should remind us that we all need God. Especially a shooting towards children that can only be defined as evil. Everyone wants to find the cause and the solution to these types of horrible tragedies. What should we regulate? What type of community program should we create?
Ultimately it is important to note that a person who is committed to committing a heinous crime will probably succeed, no matter what things (guns, knives, bullets,etc...) we regulate. There is no program or law that can prevent evil from existing in our world. We live in a broken world.
As our culture moves farther and farther from God I fear these types of tragedies will continue. We must reject the deceitful truth claims of our culture (i.e. humans are the product of evolution, marriage is not important, drugs aren't so bad, God does not exist, etc...) and to raise our children with the correct worldview. There is no other solution that will be effective. We cannot regulate or control evil, because evil is not a thing. Evil is the absence of good. You can only decrease evil by increasing good and you can only increase good by turning our hearts and minds to God. I pray for spiritual revival in our country and our world.
The probable response is going to be more gun control. However, it is important to note that crimes happen even without guns, (http://www.cnn.com/2012/12/14/world/asia/china-knife-attack/index.html). Should we outlaw knives too? In 2009, 24,518 people died from alcohol related deaths. Should we make alcohol illegal? To be fair, it should be noted that 31,347 peopled died from gun related injuries in 2009 and that 59.8% of those were suicide.

There is probably room for improvement in gun law, but we have to be careful not to go overboard. Reasonable clip sizes, consequences for people who do not secure their gun properly, etc.. but often there are already legal avenues to address those issues. Our country was founded on liberty and peopled have died to give us liberty. True liberty means having the right to make your own choices and not having the government make every choice for you. With that liberty comes the responsibility to make wise choices. We must create a culture that teaches people to make wise choices and to have a moral foundation. If I have to choose between liberty and regulation I will choose liberty every time. If you give the government an inch, they will take a mile. We have to take responsibility for our poor actions not regulate the possibility away.
