6 different tests coming back positive for C4 means it's all a mistake? Is this some kind of dumb joke?
Sprinkler parts could have many uses in the terrorism handbook if that is really what they are/were.
I think the stupid tests were wrong.
I hope they're tracing where that package has been. Possible dry run?
Wanna bet the sprinklerhead story is a cover as not to scare away passengers from cruisin'???
It wasn't six different tests, it was six tests, most likely keying on the same chemical compound (and most likely not the actual RDX in the explosive).
This could happen from having the detector set too high. I've seen someone at a trade show run a bag of spinach through one of these detectors, and it dutifully screamed "EXPLOSIVE" when it got a hit from the naturally-occuring nitrates in the spinach.
