Every state which has approved right to carry laws has had their crimes decrease to about half of what they were before the law was passed. Those instances where citizens have protected themselves, or their homes and family with a firearm, are very rarely reported. This would not support their goal to eliminate all firearms. You only get this information from those who support the Second Amendment. Firearms, knives, hammers, a piece of pipe, don't kill people.
People kill people.
The killings, robberies, etc. is within the person, not the weapon that they choose. The person must be changed or confined in jails where they cannot harm us. Our schools are safe. Our lives are full of risk. We have many people killed in automobile accidents, but eliminating the automobile is not the answer, anymore than eliminating firearms, knives, hammers, etc. is the answer.
