"Asian Couple Have Public Library Sex"

1. Is the Asian descriptor significant in some way, or is is a bit like someone being described as Caucasian in a write-up about a crime -- just a detail which has to be included?

2. Did they have sex in a public library, or just publicly, in a private library?

3. I'm trying to imagine the context in which this would be either an appropriate headline or an email subject line. I can't come up with one.
