That's true enough. Unassailable generalization, but this is a very SPECIFIC point being made with this information about Marvin Bush. This article lays the groundwork to tie Marvin directly to the 9-11 murders. But it was never followed up on. Here's another interesting article:

"Daria Coard, 37, a guard at Tower One, said the security detail had been working 12-hour shifts for the past two weeks because of numerous phone threats. But on Thursday, bomb-sniffing dogs were abruptly removed."

See, Marvin Bush had this job providing security for the World Trade Center complex, for one of the airports used in the hijackings and for one of the airliners used. His job with that security company was scheduled to end on 9-11. On Sept 6, bomb-sniffing dogs were removed from the complex. On Sept 8 and Sept 9, there were power outages in the complex (while bombs were wired). Then after the bldgs came down, there was enough incriminating evidence of bombs to convict a thousand Marvin Bushes. And to try a thousand presidents for treason. So why hasn't this happened, I guess is my point. George W, Marvin and Jeb were involved intimately with the murders on 9-11. Why are they still terrorizing us?
