Honestly, gun laws in general perplex me. Other than the necessary precautions needed when someone purchases a firearm (background check), gun laws have little effect in practice. If someone is intent on breaking a law it will happen. The answer to someone trying to kill as many people as he possibly can in a school, is not to make sure that law abiding citizens cannot defend themselves. This is common sense people. You think the people who have no respect for the law will care about the "no guns allowed" sign?
