Your assumptions that the media would be going crazy, that a fight between American factions would need to be pre-approved by the host country, that it would occur in a public place with tons of witnesses are just that. Assumptions. Did it happen? Damned if I know, but your reasons that support your claim that it is “impossible” are nonsensical. Crazy shit happens ALL THE TIME that nobody ever hears about or sees. I don’t think the media were invited to any party that might have occurred - they are part of the enemy coalition, IIRC. If the CIA was defending some location they could easily have taken out some of the attackers without necessarily being “better shooters”. In short, you are making assumptions that do not withstand scrutiny.
OH Please. If something like this were to occur in one of the largest, most advanced countries in Western Europe, the media is going to keep quiet?
This, if it’s true, didn’t happen in some Third World sh!thole or Central or South American banana republic.
For God sake we’re talking about Germany.
I’m speaking from a position of simple common sense. Something you seem to be lacking in.
