I bet watching the video evidence would be a better start than reading. Just type "JKS's death" in the search bar. I have seen some real good documentaries on the assassination. I only saw one which had pictures of the dead body showing where they stitched together the front of the head shot. I can't remember what it was, but it was the last one I saw that convinced me.
Let's think real hard about your question. Do you think that ANY military action over the passed 2,000 years by ANY military would have been successful? How would D-Day happen? How did the Japanese not just KNOW that the bombs were going to be dropped? How would ANY attack be accomplished if you think that military intelligence and knowledge would be leaked by the military. I just don't understand why you would have this question
I read somewhere that Castle_Rock is the codename for the Secret Service to protect the President. I think Q put those redlines as a warning that these if those lines are crossed, Secret Service will enact Castle_Rock and POTUS will be protected under emergency measures. Like moving him around and keeping his whereabouts unknown, etc. On a side note. Near where I live is a Highway 17, and a park called CastleRock. I go there instead of Twitter :)
