High above the MACUSA Lobby there is a giant dial with multiple clock-like faces and hands pointing to the present threat-level to the secret wizarding world. The color-coded levels include “Severe: Unexplained Activity” and “Emergency” (WFT).
Commentary
Notes
The way the threat-level changes magically to reflect the danger is remarkably similar to the Weasley Grandfather Clock in the Burrow which showed the changing location and status of each member of the Weasley family.
This is very similar to the Homeland Security Advisory System, a color-coded scale for the level of terrorism threat to the United States. It was introduced by the Bush administration in 2002 in the wake of the September 11, 2001 terrorist attacks (source: Wikipedia). -BB
