I have read from quite a few people who assert that the world would be a better place if all guns were removed. While that is an interesting thought, there are two minor drawbacks.
1) Governments are going to keep their guns.
2) Governments are going to keep their guns.
Now, I realize that, technically, that's only one drawback. But I thought that it was such a BIG one that it deserved to be mentioned twice. The reason why I think that citizens should be allowed to arm themselves is as a layer of defense against a government that could become oppressive. In short, even though I know that, for some things, we need government, I do not believe that we should ever trust government.
