From David Isakson:

Re: Catching suicide bombers and Plague as a Weapon (April 10): I just want to object to the first two stories today about war related technology. For example, the lead story about the use of well known technology to reveal concealed explosives is just that- technology, and not about a scientific process. The second article is also about war related technology rather than scientifically based. I very much appreciate and enjoy your work, but the internet is already bursting with war related stories. Thanks again though. I’ve found a lot of interesting information in your email magazine and hope to see more.
