This is so stupid.
You find luminol spots at a murderers house so full bare luminol footprints at a very bloody crime scene are not important? Yeah right.
It would have surely helped if the defense had proved them. They also could have easily figured out who that guy was that walked barefoot in the girls house if it wasn't RS. They didn't do these things for a very obvious reason.
Luminol is a presumptive test (presumptive is essentially tentative, unconfirmed) because Luminol gets false positives from numerous substances, many of them quite common. A luminol reaction is never a true positive match until it has been confirmed in the lab because of how common of an occurance this is. Steffanoni neglected to do the confirming tests after a second type of presumptive test came up negative, but lied about all of it and said that the luminol hits had to be blood. Not surprising, given her less than ethical track record.
Here's some reading material to back up my statements.

I have other ones that I posted earlier this thread or last, with lots of good quotes - if you insist, I'll go look it up when I have time and link to that too.
