UCLA identity theft

As a UCLA alumnus, I was not happy to hear that a database containing personal information of alumni, students, and employees was penetrated by a cracker recently. I didn't hear about this from UCLA (presumably, they are still sending out letters to the 800,000 affected people) but rather from Oscar Boykin, a fellow alumnus at the University of Florida. If you're a UCLA alum, ex-employee, etc., follow the link from the title to learn more about this and find out if you need to place a fraud alert on your credit report. My question: is there any reason that everyone shouldn't put fraud alerts on their credit reports all the time?
