Half of the murders is about 8,000. So 8k people use a gun as their weapon to murder. That number is insignificant when compared to the defensive uses of firearms which is over 3,000,000. That's not 3 million dead, it's 3 million times where having the gun was enough to stop the crime from continuing.
Perhaps the reason you don't believe people should own guns, is because you would use one for murder. It is in fact the person using the weapon, and their intentions that kill, not the object. So you want to allow these people, including your self, to continue to have freedom while you remove the guns from the people who use them to stop these people? You are only re-enforcing my belief that lunatics should be locked up for the rest of their life. I believe you have an anger issue. I am typing in calm manner, and you continue to hurl insults and ignore the major point I have made through out this discussion.
