Who is Gary Weinstein - The Engineer from See How They Run and what is their importance?

Nicknamed Einstein, he came to the group by way of the CIA from Harrisburg Pennsylvania, the Honeywell Corporation and the Virginia Institute of Technology. He was easily considered to be the most brilliant of the terrorist group, and also likely the most unstable. To perfect the electronics for Dachau Two, he spent two-and-a-half years working in a DC garage in Washington. He seldom got a chance to actually see his work, but Moscow was different. It made him feel a little bit like the hell raiser he used to be in his old hometown of Harrisburg.
