I've been following your responses in this thread. I do agree with you but you make it seem that it's almost impossible to blend in now. Based on this, wouldn't it be almost impossible for intelligence agencies to develop human sources in modern countries? They could just trace the case officer back to their home base or just classify them as a spy based on other patterns? Doesn't this mean that human intelligence is practically dead in 1st world countries?
