When a murder is committed using a knife, do we try to ban knives? When someone intentionally drives their car into oncoming traffic to commit suicide, do we try to ban cars? When someone sets a fire to burn down a forest, or a building, or to kill others....do we try to ban matches?
Firearms are dangerous for sure, but PEOPLE make decisions. Our founding fathers were some of the world's most brilliant people, EVER. The right to bear arms is there for a reason. We can debate the reasons, but IMO its largely based on the concept that a government should not be in control of the people. The people should be in control of the government.
