> Again, doesn't every p2p application share by default?
Yes, I think so.
> Is there any evidence that she wanted to share?
She knew what she was doing. She had written a paper about Napster's forced closure. In that paper she argued that it should be legal, so it's quite clear that she knew that filesharing copyrighted material was illegal. And she had password protected her computer, which showed that not only did she have control over the software on her account (she actually put the blame on her son during the trial; absolutely shameless, this woman), but that she was not a complete neophyte on the computer. Claiming ignorance just isn't convincing in this case.
> she likely would have gotten less of a penalty if she had indeed shoplifted these cd's and then sold thousands of copies on a chinatown corner
True, and rest assured, if a significant amount of people start engaging in this kind of behaviour, the RIAA will go after them too. My point? Filesharing is making the industry bleed. That's why they're going after it.
> She wanted to download and listen, not share, this music.
She downloaded 1,700 tracks. She shared 24. Those are the facts. It's impossible to know what her intent was, but my feeling is that you're being unduly lenient towards her behaviour.
