Next of Kin was a pretty interesting "bad" movie. I remember seeing it on HBO or someplace a few years back and found the way they handled the family network very interesting.

Your point on the Mafia don who uses 3x5 cards is well-taken. High tech can only really defeat someone who chooses to meet you on those terms. If they avoid engagement there, you have problems. One example that folks tend to forget is operations against the Ho Chi Minh trail. The most successful ones were directed or initiated by SOG teams on the ground. The least successful relied on high-tech AF gear that could be fooled or tricked (although this also played into the AF reliance on numbers to quantify their Trail operations...the book "Setup" by Tilford goes into some interesting details about this).
