He tells them to make assumptions not in evidence. The only reason there has not already been a mistrial is that DW stands to make more money by being falsely convicted, then exonerated that by having the case thrown out.
All of the relevant evidence that has been suppressed by LE WILL COME OUT eventually. Did the caller on the 16th have a hispanic accent? Were some of the hairs in the RV Brenda's? The VD's prophetic comments about finding the body are more incriminating than DW unrecorded alleged comments to LE.
DW will be Emperor of San Diego when the dust settles from this. Some LE belong behind bars, not just reprimanded.
