The same building exterior (aerial shot) is used for the Serbian embassy in this episode and the Turkish consulate/secret bank in episode #1.3.
Coat of arms visible at 27'05'' should be Serbian but it is not.
In Legitimate Target, "Rado" is supposed to be typing only binary code, but he is actually typing random numbers on the keyboard.
When Rado is in the Serbian Embassy typing on the computer he is typing only 1's and 0's according to the screen output, yet he is only hitting keys near the 1 and 2 on the keyboard.
