Oy vey.
Guns have one and only purpose: to injure or kill whatever they're aimed at. If used correctly, they'll do just that.
Cars have several purposes: to move people from Point A to Point B, to move cargo from Point A to Point B, et al. If used correctly, they'll do just that.
Cars used incorrectly or for purposes other than what they were designed will cause injuries or fatalities. It's why auto companies spend millions developing better safety equipment, better frames, and new technologies to improve driver and pedestrian safety. It's also why there are laws to ensure people operate their cars properly, so they don't injure themselves or others. There are penalties specifically for crimes committed with cars: vehicular homicide, driving under the influence, and countless traffic laws.
There have to be laws governing the use of guns just as there are laws governing the use of automobiles. You're restricted from driving over certain speeds on public roads because it poses a hazard to other drivers. You're restricted from raising vehicles over a certain height because it poses a risk to you. On the same hand, you should be restricted from owning certain weapons and carrying them in certain places. You can go to the gun range just like you can go to the race track.
Guns don't kill people, people kill people; if guns are outlawed, only outlaws will have guns.
Guns don't kill people, but they sure make it a hell of a lot easier. The whole point of making certain guns illegal is to make sure ordinary people can't get their hands on overly-powerful weapons that make killing others easier.
The best idea is probably not to ban guns or make them harder to get, but to increase safety and awareness through mandatory classes, like with driving.
That's a temporary measure. The best way to end gun violence is to eliminate the root causes of crime in general: poverty, unemployment, poor healthcare, and urban decay.
Unfortunately, the same rabid Second Amendment activists tend to be in the same crowd that view those measures as "socialist" or bad for America. They've become their own self-fulfilling prophecy by ensuring a constant need for guns to protect against the crime they have no interest in ending in any meaningful way.
