That is tin foil hat nonsense even by prior low standards, but why would LBJ need a signal? Even if he was involved in the assassination plot, he would see for himself if anything happened. He was in the motorcade. He wouldn't have any action to take in the act other than to become President if it succeeds. If he needed a signal, however, why couldn't it be yellow roses? I will give you some credit though. Some sources suggest LadyBird's flowers were white but they do appear to be yellow in the color photos. The flower on LBJ's suit is white.
Yeah, this takes the cake(bread)... surely one of the top OMG moments in tin foil hat history
And yet, you can't explain why Mrs. Johnson received yellow roses while Jackie Kennedy received red roses when she received yellow ones the day before.
Who said that the signal was for LBJ besides you? It would have been for the sniper teams.
It's difficult to piece together your ramblings. The roses were given to Jackie at Love Field. Are you saying your fantasy "sniper team" needed a signal at Love Field? They then jumped into their cars like the Wacky Racers and headed to DP to set up the kill? Are you goofing on us to pass the time? If you think there is even a one in a billion chance that anything like that happened, it is not a healthy sign. As for LBJ, check with your kindred Walt. He suggested LBJ was getting a signal.
