Go to the truck outside of the entrance to Claire's prison cell (where the very first zombie popped out of). Inside is a case. Inside the case is some kind of alloy that cannot be detected by metal detectors. Head back to the room where the Hawk Emblem is. Put the Hawk Emblem and the Alloy in the duplicator machine. Run the machine, and it will drill the Alloy into a replica of the Hawk Emblem, which cannot be detected by metal detectors so you don't have to put it in a security box when running through the security area.
Let me know if I helped you. If not I can be more in-depth.
