Grassy Knoll?
The only grass in Cairo is marijuana.There may be a few knolls, I have never been there and never will be.
I do have a personal friend , a retired naval Captain who was on the review stand as a US Embassey military Attache representative, when Nassar was assassinated. His military colleague sitting next to him took a rifle round through both buttocks, as they both hit the deck.
He says this whole thing is an Obama set up.I believe him.
