Ghost and Taskforce 141 was protecting a school that had been sent bomb threats. The same school was the one you are at.

I walk through the halls patrolling the school building. I few scared students walk around me nervously and whisper to themselves, I could care less though. I walk by a few of the classes, looking inside them. I catch some teenage couple making out and tell them to leave, they get nervous and jump. But leave all the same. I then leave that room and look through the others.
