When you get the likes of the MPAA dragging some poor granny ( who doesn't even have broadband! ) through the courts based purely on an IP being used to torrent a single movie, I can't say I have much confidence in these sorts of laws to do anything but get innocent people blamed. The "pros" know the game and for the most part, they're careful with their supply chains preferring to "offload the uploading" to sub-ordinates who simply want to be part of what those of us old enough to remember, used to be called a "warez crew".
