There is more than one problem with this argument. The first, and most glaring issue, is that criminals have a long track record of not following laws that are made. Oh hey, I think that's actually what makes them criminals. Don't believe me? Look at what has happened in Chicago, where they have worked to effectively become "gun free". Chicago has two very clear, and very parallel, reputations; the toughest gun laws in the U.S., and the highest per capita murder rate in the U.S. (mostly by firearms). I guess somebody forgot to tell the criminals that guns weren't allowed....
Today, I believe my cynicism was proved. I took the time to begin searching for stories about gun use in the news. There were a few stories here and there, some about guns accidentally hurting somebody, or being used in a crime. Occasionally there was the story about police using their guns to end a crime spree. But the one that really caught my attention did so because of its lack of coverage.
Buried about 20 pages into my search was a "BREAKING" story from the previous day. The story occurred in Florida, where a deputy had been involved in a high-speed pursuit. According to witnesses, the suspect jumped out of his vehicle and grabbed the deputy from his patrol car, throwing him to the ground. The suspect proceeded to mount the deputy and was demolishing him with violent punches.
Another citizen exited his vehicle, promptly unholstered his concealed firearm, and ordered the man to get off of the deputy. Witnesses indicated that he did this more than once. When the suspect refused to comply, the citizen shot him three times. Results: suspect is dead, deputy is expected to make a full recovery in the hospital.
What makes this story sensational is that it wasn't. This is a story of somebody that is clearly well trained with their firearm. They recognized the same thing others had reported, that this suspect was putting people's lives in danger earlier. This well trained citizen also understood that jumping out of your vehicle with guns blazing is not appropriate. He gave the suspect more than one opportunity to cease his actions. When all else failed, he unloaded three well placed rounds. In order for all of these things to happen, this person had to take the time to get good training.
So is it safer for us as a society if we ban guns? NO! What makes us safer is knowing that there are people, not just professionals, that take the time to be responsible gun owners. Getting trained in the laws of firearm use, as well as the practical skills associated with using them in self-defense or defense of another. If everybody took the time to do this, we would virtually eliminate two things: 1) "accidental" shootings and 2) helpless victims attacked by a criminal with a gun.
