It seems to me that so much time is wasted between the pro-gun control and anti-gun control sides. Guns simply will not go away in America in our lifetime. Personally, I don't have a problem with a mature, responsible citizen carrying a gun. But, the clear fact is that illegal gun use takes more lives than civillian gun use saves.
There has to be a common ground here and I think it would be as easy as simply enacting and enforcing stricter laws on illegal gun use. If you are in possession of a functional gun without a permit, manditory 5 year sentence. If you are caught in the act of using a gun in the process of committing a crime, manditory 20 year sentence added on to your sentence. If you sell guns illegally, manditory 5 year sentence per offense. These are all examples, but I believe they convey my point.
I know that this won't solve every problem surrounding gun violence. For example, domestic violence involving gun use would most likely stay the same, disgruntled employees would still be able to lose it and go on a shooting spree. However, these are situations where the criminal would most likely still commit these crimes with an alternative weapon. Anyway, it may not solve the problem, however, I think its at least heading down the right path.
