Still, isn't it fairly common for copyright infringement to
be a criminal rather purely civil concern in countries other
than the US?
Interesting point. I wonder what it is about copyrights that makes it the only candidate for criminal status rather than purely a civil cause of action. To me, criminal punishment for IP infringement is a little too reminiscent of debtors' prisons that have long been done away with.
I think the answer lies in something I heard with respect to the Eldridge case -- something along the lines of ... in the US Supreme Court, when has right prevailed over all the money in the world? Usually, those two aren't pitted against one another, but when they do, there's a clear winner.
What you have in copyrights that I don't really see anywhere else (yet) is copyrights and little else pooled together into an extremely profitable business venture (e.g., the RIAA members). You have some very very wealthy people and institutions with very strong interest in strong copyright protection. And lobbying of Congress has been shown time and time again to be very profitable.
There are signs of a similar evolution in patents where some groups are buying up under-utilized and under-enforced patents with an eye toward aggressive enforcement of patent portfolios with little or no other business model. If they ever get big enough, you'd better believe you'll see some heavy lobbying for very very strict enforcement of patents with a lot of pro-patentholder legislation.
I'm not saying that's necessarily a bad thing, but it would be significantly different from what we have now. And, if the difference appears to be directly resulting from a large concentration of money in the hands of a few organizations, you have to ask yourself if other constituencies and the public at large really benefit as much as they ought to.
As usual, I don't have the answers, only questions.
