Legal? Constitutional?

[T]he Christian’s morals are not determined by whether something is legal or constitutional, but by what the Story of God in the Bible reveals. A Christian citizen may think civil unions are legally permissible on the basis of legal precedent or legal gaps, but constitutional legality does not determine what is right or wrong, regardless of how much citizens are to respect or live within that law.— Sermon on the Mount, page 74

And I would add to that the issue of gun control. Sure, it's legal and constitutional. But why do we need automatic weapons? So we can kill. Hmmm...something wrong here, isn't there? I think I read a few different places in the Bible that it's wrong to do that...
