What if you googled a job applicant and found out something?

What if you found out something about a job applicant (or even a current employee) on the internet? How would you use that information?

Harvard Business Review has published its first-ever HBR Interactive Case Study. The case, which is fictional, deals with what a company CEO should do when he discovers (via his HR manager's Google search) that his preferred candidate for managing his first China branch, was convicted 8 years ago for protesting over China's treatment of a dissident journalist .

HBR will publish the best submissions online after the case “closes” on June 15, 2007. But you can see a selection here. What would you do?
