When I was 14 years of age, I bought a .22 rifle. Most other kids my age had a rifle or maybe a shotgun, did some hunting and target shooting. We also carried pocket knives. There were no laws against buying a gun or buying a loaf of bread, the gun cost more. No gun, knife, golf club, ball bat, piece of pipe, ice pick, hammer, ever killed anyone.
People kill people.
These are only the weapons used. Trying to get rid of all the weapons does nothing, the person must be changed. If the weapon did it then convict the weapon and free the innocent person. For 40 years or more, we of the United States have been programmed by our government, ACLU and others to have no regard for things of a religious nature - no prayer in school, gideons no longer able to speak in our schools and give Bibles to those who desire them, no Ten Commandments on public property or Court Rooms, no prayer permitted at graduation. If people become Godless - no belief in God, the Supreme Ruler of the Universe, Jesus Christ, or a religious belief, there is no anchor, no reason for mortality, honesty, truthfulness, etc.
