Re: Hating the wrong people
1) Copyright is not lost if 'undefended'
2) Even ISPs using real time deep packet inspection (very expensive to implement and maintain) have very little chance against an encrypted data stream. Your assumption otherwise shows how technically ignorant you are.
3) Profit lost to copyright holder for an instance of a downloaded film might be £10 (total guess), but money paid by law abiding citizens to keep someone in jail is likely to be in the 10s of thousands, even for a short stay. While they are in jail they can also sit a degree at our expense :) Might be fair if the movie industry paid the bill for the jail time - lol.
