Actual exchange between Fulcanelli and halides1:
Welcome back, Fulcanelli!
I don't know about the rest of you, but when I look at the video of the forensics investigators "finding" the bra clasp, I wonder how there was any DNA left on that sucker to test. After allegedly plucking it from the pile of debris into which it had been swept, the officers touch every surface of it repeatedly, turn it over and over and over in their hands, hand it back and forth to one another in dirty gloves, put it down on the floor, flash camera strobes and shine hot lights on it for long periods of time -- they might as well have stuck a fork in it and roasted it over a campfire. Then they extra-carefully place it in a little plastic bag -- you know, so it won't get contaminated?
Raffaele's DNA is so easy to disturb that he and Amanda managed to clean up every single, last, itty-bitty trace of him from elsewhere in the house. The microscopic speck on the bra clasp, though -- man, that was one tenacious strand of deoxyribonucleic acid!
