Arguing whether or no the laws are fair is a moot point, just as is arguing a speed limit of 35mph when everyone else drives 55, and you get the ticket for doing so. The copyright laws have been in place forever, but nobody gave a hoot about them until the advent of computers, mp3s, and file sharing. From the reading I've done on the subject, the target of the record companies is not necessarily the people who downloaded music, but rather the ones who shared all of their files. To the best of my knowledge, you had the option to NOT share files, or at least direct your downloads to an unshared folder, which would more than likely circumvent being noticed by the RIAA. Still "illegal", but usually out of harm's way.
It's not the 24 or 26 songs they used in the trial, it was the 1700+ songs she was sharing, most of which were "protected". To make matters worse, the RIAA set up their own account with the file sharing program, and downloaded songs from her. They then sent her a PM through the site informing her that she was violating copyright laws, and to stop. She ignored them. Then, after receiving a subpoena, she swapped her hard drive, and claimed she knew nothing about it. AND, she had the option to settle out of court as did most of the people who have been contacted. (mostly in the $3-5000 range)
Her main claim was that she didn't know anything about it, and somebody may have "hacked" her account. Obviously the jury didn't agree.
