Penn State University student LaKeisha Wolf has a professional bodyguard, sometimes two, at her side most days. The 21-year-old broadcast journalism major rarely steps out alone.

Wolf, president of the university's Black Caucus, has received four death threats in the last two years, including two in October. So six months ago, Penn State offered her protection.

``Because they're anonymous and because they're so vile in content, I think any reasonable person would be scared,'' university President Graham B. Spanier said. ``That fear, that legitimate fear, is something that should concern all of us.''

But Wolf isn't the only black student who's been threatened, and some students complain Penn State isn't doing enough to address the problem. Their anger has touched off a firestorm on this rural central Pennsylvania campus, where some say there's an undercurrent of racism.
