you remember the saudi suspect kind of washed out. so the perpetrators are still out there, and every day that passes, the case becomes a little bit colder and more difficult to piece together. but i'll remind your viewers, though, the 93 world trade center center bombing case was masterfully put together by the fbi and the u.s. attorney's office where they pieced together this forensics from the bombing device at the world trade center and were able to attribute that back to the terrorists, that would be ramsey yousef and the blind sheikh at prerp perpetrated that. i do think there's more of a sense of optimism between the fbi and joint terrorism task force in boston that they're getting closer. >> sir, thank you very much, good to talk to you again tonight and we appreciate you taking your time.
