Nom,
It's stated the R's attorneys were treating their own clients as potential 'Defendants' in various written literature on this case, including the book PMPT. I am assuming these attorneys realized that finding a dead body in their clients' home was potentially NOT indicative of an intruder having committed the crime, given the nature of the ransom note and all the other evidence leading away from an intruder theory. I say this tongue-in-cheek, as any professional within the legal/police system know all too well that in homicide cases such as this, it is generally recognized that crimes of this sort are 'usually' committed by those of whom the victim knew on a personal basis.
It's called strategy; the lawyers hired by potential criminal defendants in a case will employ whatever strategy they feel will best help to DEFEND their clients.
GUILTY parties are represented by lawyers all the time and don't think for one darn moment that those various attorneys defending these same parties, DON'T REALIZE THAT. Of course they do...
The strategy employed by the Ramsey Team was to treat them essentially as Defendants. It was this very strategy which then led the attorneys for the R's to insist that their clients be given certain evidentiary materials PRIOR to allowing them to be interviewed by the police department. Police department personnel and personnel within the DA's office recognized this strategy for what it was and played their various hands accordingly.
Please understand, like it or not, that trials in our courts of law have absolutely nothing whatsoever TO DO WITH THE TRUTH. Trials are a game of strategy; one upmanship, if you will.
And yes, financial consideration does play a part as to how well you are represented in a court of law.
As I've stated, this is decidedly NOT a perfect system; it is what it is.
