Caprio 101. Make a ludicrous, baseless claim like the roses were a "signal" and then ask others to "explain" it to his subjective kooky satisfaction. You claimed it was a "signal" to a "sniper team." Why don't you explain that with "supporting evidence"? It's absurd. There is no significance to the roses that needs any explanation. You should be ashamed.
It's NOT baseless as you falsely state. The entire trip, which included other motorcades, Jackie Kennedy received yellow roses, but in Dallas she is handed red roses. Why? Your failure to answer this question shows that you are the one making baseless statements.
For many years it was said by WC endorsers that they were out of yellow roses, but this is false (or a deliberate lie) for two reasons. Firstly, as I stated KLIF mentioned that Lady Bird Johnson received yellow roses (and this is supported by a photo that shows she is holding a bouquet of yellow roses). Secondly, the radio announcers said that the roses were flown in from California for the special occasion. Since they were flown in it is impossible that they were out of the yellow roses.
Once again you post nothing of value post after post.
