What should you do if you know someone breaking the copyright law?

I have to write a report for school about a person (John) who buys a computer game and then copies it and sells the copies.

What should I do if I know that a friend is breaking the law. I'll explain to him that he is breaking the law and that he should stop. But should I report him? If so, where?

Report it to the local police department. They might give you a cookie for doing it. Perhaps a few late night visits to see if your defying the patriot act. Unless of course you live in austin... Well idk about that...

Have them whacked by some desperadoes.
