Doesn't quite make sense, as copyright is tort, but there are police departments devoted to court enforcement. I'd be wary.
Not saying it will happen, but seems easy to catch a lot of people with the draconian powers and laws of UK.
Then they demand that isps all over the country give names and addresses of people all over the UK that broke no law and did no wrong in hopes of conducting a fishing expedition and don't get laughed out of court.
Now they know who pays the bill for each home network but have no idea who actually downloaded the perfectly legal metadata and no way whatsoever to correlate the data of unknown users of the data with potentially unnamed buyers who legally purchased mp3s from multiple channels like Apple but you think a judge is going to let you paw through every computer in someone's home because you think they probably ripped a cd instead of downloading it on itunes 6 years ago on a different computer at a different address.
Does this sound real?
"Wronged" implies that they were harmed in some way. A better term would be "offended". They discovered, indirectly, that someone else was doing something they don't approve of—which otherwise doesn't affect them at all—and they want it stopped by any means necessary, even though this will just make the other person worse off without materially improving their own situation.

There are 100 different jurisdictions and while the law is different the practical situation is the same. Who is exactly going to police you copying your own cds in your own home? How is bob from bob's records to discover you have copied it? One should have to convince congress to require Operating systems to rat you out to bob then convince users to use such systems.
