I think most people by now understand the difference. The real question is do we want (what I will call) common copyright infringement, which is already against the law as a civil matter to be criminal fineable or jailable offense.
But now, do we want common copyright infringement infringement to be a crime?
I think most hear can agree that using someone's copyright against their will is wrong. But is it a moral wrong, a civil wrong, or a criminal wrong? Clearly those who own the copyrights don't want others using their copyrights without their authorization/compensation. But is this a battle that we want the government involved in, criminally? Some copyright infringement already is criminal. Remember all of those FBI warnings at the beginning of DVDs? If you start selling copyrighted materials as your own, you could be going to jail. And I think we call all agree that this is a crime. Clearly in large scale infringement cases, for example Microsoft using some Apple copyright, a civil proceeding is warranted and suitable.
But what do we do with individual offenders? The Pirate bay types. What type of crime is is? A moral one like adultery? (used to be a crime, but is not anymore **exceptions noted**) or should it rise to a punishable offense? What is the line between the two?
These are the questions we should be asking ourselves and as a society and not allowing special interest groups to drive the discussion.
