My sense is that Q was speaking metaphorically about the the gun, i.e. who was Obama aiming the gun (weapon) at., not an actual photo of shooting a flag.
The cabal like to have leverage over people, the same as gangs do. Get someone to do something really bad and document it and you will have leverage over them for life. With that in mind I fear that perhaps Obama actually shot a person. Q used the word who and not what. A flag would be a what, but a person, in real life or on TV could be a who.
Any speculation on who?
My guess from the way things were worded was that it would be someone that we recognized or else that caused great shock - such as a small child.
If it’s a recognizable person, the one that springs to mind as a possibility is Ron Brown. I’m not making a case for that, because there are probably other possibilities, but it would be interesting to know where 0vomit was at that time. ;-)
