I am not sure if the person who did the presentation on copyrights and downloading the other week mentioned this. To tell the truth, they could have talked about puff the magic dragon and I would not remember at this point. My brain is too fried - curse you finals week!
Anyhoo, a prosecutor in Sweden has vowed to file charges against The Pirate Bay on the grounds of breaches of copyright law. Apparently this group of people are BitTorrent's foremost trackers and were raided about a year ago, when police confiscated servers and other computer equipment.
