SANTA CRUZ, Calif. - The protest was carefully orchestrated, planned for weeks by Students Against War during Friday evening meetings in a small classroom on the University of California campus here.

So when the military recruiters arrived for the job fair, held in an old dining hall last April 5 -- a now fateful day for a scandalized university -- the students had their two-way radios in position, their cyclists checking the traffic as hundreds of demonstrators marched up the hilly roads of this campus on the Central Coast and a dozen moles stationed inside the building, reporting by cellphone to the growing crowd outside.

"Racist, sexist, antigay," the demonstrators recalled shouting. "Hey, recruiters, go away!"

Things got messy. As the building filled, students storming in were blocked from entering. The recruiters left, some finding that the tires of their vehicles had been slashed. The protesters then occupied the recruiters' table and, in what witnesses described as a minor melee, an intern from the campus career center was injured.

Fast forward: The students had left campus for their winter vacation in mid-December when a report by MSNBC said the April protest had appeared on what the network said was a database from a Pentagon surveillance program. The protest was listed as a "credible threat" -- to what is not clear to people around here -- and was the only campus action among scores of other antimilitary demonstrations to receive the designation.
