Amazon PR guy's behavior is debatable and has been debated, but this article and its misleading title do not improve the debate. HN itself is host to dozens of Amazon employee/critics that have not seen personnel info leaked. also, "criminal activity" is a bit beyond "personnel info". Am I leaking personnel info when I tell someone about a coworker who scammed a customer?
It you're the employer making the allegation, you can be sued.
