I'm no expert, but even in an explosion I would doubt that the reaction would consume 100 percent of every material. Even the inability to measure perfectly would come into play.

Time will tell I guess.

I'm obviously not an expert on these things either, that's why to me hearing that there is no residue to even figure out what the bomb was made of is rather intriguing(sp?). I wouldn't think it could burn off 100% either.

I'm hoping there are some chemists or munitions experts here at FR that can give us insight (not how or with what), but to tell us if it matters, and even if it is possible...

My first layman's thought would that it would be hard for them to prove in court that someone created and intended on setting off a real bomb vs. a hoax. If you've got no proof of explosive residue (as is apparently the case at ECU) there would be no way to prove that the "suspicious package" the bomb squad set off was indeed a bomb...
