Dear Mr. Shriver:

Thank you for inviting me and Mr. Jim Murray, of the Tucson Police Department, to observe a series of demonstrations of the capabilities of the Explosive Mobile 1 (EM-1) System and the Fixed Security Screening System (FSSS). While I am writing this Report to you based on my observations and conclusions, Mr. Murray has authorized me to state that this Report also reflects his own observations and conclusions. I am very impressed by the systems and their potential to significantly improve our national security as well as to disarm former mine fields. I will describe my observations below, but let me say at the outset that I observed a total of some seventeen trials, mostly consisting of five "shots" each and I observed 100% accuracy. That is, there were no false positives and there were no false negatives and each trial produced an unambiguous and definitive result.
