Interesting question @sprotz - Personally I suggest that that particular embassy would have had at least 4 permanent USA surveillance staff surrounding it 24 hours a day - with “Pick up” personnel and vehicles on permanent call out within a few yards.
The fact is that you and I (for daring to speak of such matters) are now in an NSA database of “Watch these” just for our interchange on this site. Secrecy and subversion dominate “Ministry of truth”
But J A - for providing a resource where people could actually tell the truth is unliikely to see the light of day for many many years !
An individual’s right to life in this world is measured in regard to the amount he (I would have put the “s” in - if I was lesser man ! ) is prepared to take a moral stance !
