BBM: Hey, Dave, bear with me, sometimes I'm a little slow on the uptake, but if I'm understanding you correctly, you are saying that we should speculate that they found no forensics because they said they didn't need to do the testing on small sized samples? Couldn't it be the case that when they went in with Luminol at night to KB's the walls/floors/ceilings all lit up with evidence that PF thought he concealed?
Also, I'm wondering if they could still do the charcoal blowing stuff there even though it's an antiquated procedure. Sometimes there's no substitute for good, old-fashioned police work!
