A woman with the pseudonym Amy Unknown was at the Supreme Court on Wednesday as justices discussed the horrible events that changed her life: Her uncle raped her when she was a young girl, recorded that assault and other sex acts and put the images on the Internet, where they have been viewed tens of thousands of times. All the justices seemed to think that those who downloaded the images of Amy should pay to help her put her life back together. But they struggled to decide what any one person should pay.
