How Many People And Fire Rescue Personnel Died When Building Seven Collapsed?

 ZERO.

At the time of the collapse....5:20 PM.....no one was inside.

Among the 40-odd resident organizations in the structure?  Central Intelligence Agency (CIA): (Operated a clandestine station, never fully disclosed), the Department of Defense (DoD) (again never fully disclosed), the Secret Service (maintained a presence, likely for security and investigative operations),and the Internal Revenue Service (IRS).  

Just odd....every single person was told to leave, and no firemen allowed to enter.
