In Langley, Virginia, USA...
The CIA main headquarters in Langley, Virginia, USA has a building within a building. The outer "shell" is the normal perimeter glass...the inner building as well. However, the CIA plays music between the two buildings so someone with a laser bounce device cannot recover any conversation happening inside the inner building. I also understand that the inner building is a Faraday cage to suppress any and all signals.
