The Viet Cong spoofed American sensor technology in Vietnam by hanging bags of urine in trees and playing tapes of truck engines.

The early seismic sensors that were dropped along the Ho Chi Minh Trail were designed to look like dog turds; this was cause for much self-congratulatory "aren't we clever lads?" backslapping until someone pointed out there were no dogs along the Ho Chi Minh trail.

Then there was the soap compound the USAF dropped on the trail. “The application of a harmless dry powder which breaks down soil stability along the HCM Trail” was designed to turn the roads into impassible goo. I'll let you guess how that worked out.

Naturally we're far cleverer today. However, once budgets are diverted into buying units of this very impressive type, it will be a source of great amusement to me to see what low-tech solutions to confound and counter them are posted on the internet.

I have no idea what it would look like. Idle speculation says that it might have to do with the fact that some chemical compounds enjoy being microwaved even less than people do; perhaps inspiration will descend from observing what happens when you accidentally leave a spoon in a microwaved bowl of soup. I can guarantee you, however, the response will be vastly less expensive than the device itself.

Unarmed London Bobbies kept order with force of personality when the bulk of the populace was reasonably content with the hand that fate had dealt them. When they aren't - well, Baron Haussman had to essentially redesign Paris in an attempt to keep the mobs in check.

Like most "miracle weapons", success in any sense broader than the minutiae of tactics is ultimately determined by the social fabric in which they are embedded - how palatable the causes are in which they're deployed, how determined and broad-based the opposition to those causes.

As an aside, it took me about 10 minutes research to figure out how to create a set of clothes that would be taser proof. I'm honestly thinking I might splurge and have a set made up, especially as the cost isn't all that expensive (less expensive for those of you who can sew well enough to make your own clothes.)

Wouldn't have done it before, because tasters are supposed to be "what you use instead of shooting people", but since some cops seem to like using them as torture devices...
