TARDIS console rooms, in any of the known configurations, is the TARDIS console that holds the instruments that control the ship's functions. The appearance of the primary TARDIS consoles has varied widely but shares common details: hexagonal pedestals with controls around the periphery, and a moveable column (or time rotor as it has been called in the original series and the 2011 episode "The Doctor's Wife") in the centre that bobs rhythmically up and down when the TARDIS is in flight, like a pump or a piston. The secondary console was first seen in season 14 (1976–77) of the original series.
Blue wall of silence Blue wall of silence The blue wall of silence, also blue code and blue shield, are terms used in the United States to denote the informal rule that purportedly exists among police officers not to report on a colleague's errors, misconducts, or crimes, including police brutality. If questioned about an incident of alleged misconduct involving another officer ("e.g.," during the course of an official inquiry), while following the code, the officer being questioned would claim ignorance of another officer's wrongdoing or claim to have not seen anything. The code is considered to be an example of police corruption and misconduct.
