I'd be rather interested to know how they will prove in first place the person actually did download pirated music.
1. how do they know it was the person they're going to send the bill? (human right organizations will love to whine about this)
2. how do they know it actually was illegal? As far as I know, the routers only knows what file names along with the filesize were sent, not the contents.
This should be proven, but I don't see how you could.
3. how do they excuse monitoring people's traffic?
It's not like you have the FBI standing at the door and scanning every container going in and out of the house - monitoring someones file transfers is quite bit similar to this... intrusion.
Theres some to begin with
Will be interesting to see how they excuse those and prove it.
Any intelligent person who reads news, will erase all illegal music files from his comp and bury the CD's somewhere where the house warrants doesnt apply and write over empty space on their HD or use advanced format.
