Can you elaborate? (April 19 was the date of the Oklahoma City bombing, of course; this is generally attributed to its being the anniversary of the assault on the Branch Davidians in Waco.)
Remember Ferrakhan's "Million Man March" several years back? He gave a sermon on the number "19". In fact, this business on "19" runs back centuries although I have not examined that aspec thoroughly, but someone undoubtedly could use the Net for that purpose.
We also have the Waco thing on the 19th, and the Murrah bombing on the 19th.
You will recall that throughout the investigation of the anthrax attack I have pointed repeatedly to the fact that there's somebody in the FBI who doesn't want anybody to make a clear and convincing connection of the attack to Mr. Atta and his friends.
We seem to have found such an individual in the identity of the Deputy Director at the FBI identified in the New York Times news article that precipitated this thread. He, of course, would have been in a position to "pick the date" for the Waco event, and possibly also for the "Murrah Building", if he were involved in somesort of deeper conspiracy.
OK, finished stepping off the planet?
Good, so am I!
That particular connection was made by dwelling on the number "19" all by itself. Actually, you have to focus on the whole date business and use some basic math. 9/11 and 11/9, as well as each written right to left as 1/19 and 11/9 would also be viable. The Homeland security folks gave us warnings on or about 11/9 and 1/19. Obviously someone there thinks 9/11 has meaning.
Then, we have the Moslem lunar calendar to look at. The same sort of dating analysis would give you other respectable "hit dates" for major events.
Homeland security also spoke up on those dates.
If you recall the problem with the Reverend Jim Jones down in former British Guiana, you would have instantly realized that he started out in Indianapolis, moved to San Fran, then moved as far East of Indianapolis as you can go, which takes you to Guiana in South America.
This sort of behavior, balancing geographically, or using number magic that begins with something already publicly known, e.g. "911", the standard emergency request number in most of the US, is fairly definitive of a type of schizophrenia. Combine that illness with bi-polar disorder, and maybe an homosexual predisposition, and you have your charismatic leader who will undoubtedly pick up a cadre of like-minded or confused people. That is, you have a crazy Mr. Atta and his band of killers, and they are not really any different than the Reverend Jones and his band of killers.
Osama Bin Laden most likely financed their operations, but there is a very good question about how much he knew of these people. This doesn't make him innocent since he was out there hiring murders to be done, but it makes him less than some sort of charismatic mastermind. Instead, he becomes nothing more than a murky figure with questionable morales and a pile of money. He pays for charisma.
On the other hand, there may be a number "19" fan in the FBI making serious recommendations, and he's still on the loose. Possibly he was Mr. Atta's "control" or his "date".
