The shirt cuff, of both the pj's and purple shirt....not sure why Feldman was saying ankle but it may have been why he was objected.
Now, Danielle's PJ's had a bloodtype stain on the anklet. My guess is that Danielle had a scratch from the dog or something that DID BLEED (obviously, on the PJ's) and since Damon and Brenda both were trying to say those Pj's, laying on Danielle's floor, inside out, were NOT HERS, that would mess up their story. SO,somehow they had it already established that Defense couldn't bring that up as there was no proof, because the LE's test didn't come up with Danielle's DNA from it. Because someone (LE) didn't want it to.
