the problem is that there is sooooo much, there is no way to review it all.
a writer in NY and a writer in LA had phone calls back and forth using scriped conversations. they used the special words. both were visited by men in black suits.and that was when the internet was less than 10 years old.
anyone notice that this thread is 3 pages long and no one is discussing any actual devcies ?http://www.figarosensor.comfigarosensor makes multiple gas sensors. not sure if there is one as sensitive as a dog.metal detectors can find metals.the question of a belt with the wrong stuff, is there a sensor that could tell if a human was wearing a coat (or clothes) or carrying a book ?

I have about 20kg of a very dangerous material - LPG (propane?). Easily obtained. Easily detected by the nostrils. Not so easy to hide under clothes.
