Trampled symbols

Exploration Stage: Octopus Citadel
From: Mr. Black
Description: I wouldn't feel safe walking around the building until I've checked out the points of concern. For example, the Security Department flag is missing. It was displayed in a prominent place at the entrance to the building. Did the Shadow disciples rip it off when they raided the building? Look for it with me!
Completed: Did it fall on the floor? And there's even shoe prints on it. It was definitely the cult's miscreants who pulled this off. I will never forgive them. It is nothing but an insult to treat an important symbol of the TSA like this!
