In my opinion the main purpose of the press conference today was to let the public know that the family and friends on those search warrants were not suspects. It may have even been a request of a lawyer of one of the couples who have been smeared or the family. They should have done this sooner then later. JMO.
I have no exact theory. What I do have is the idea that we should be careful what we wish for. We all wished for a presser & we got it. What we really should have wished for was presser announcing an arrest!
