Scarlett, my dear, you are reaching, to put it mildly. Patsy herself thought she would be arrested - even joked about looking fat in jail garb. The Ramseys were so prepared to be arrested, that they made arrangements to have John's brother become guardian of Burke, if necessary. Guess they must have worried that someone might have slipped out of the web of "spin" and were allowing for the odd chance of a shred of truth getting through to interfere with the subterfuge that was carefully crafted to keep them from having to face charges.
The combination of a gutless DA, followed by an incompetent DA, plenty of expendable cash, and a powerful legal team worked it's magic in keeping the Ramseys from seeing the inside of a jail cell. There was a vote to indict handed down by the GJ, yet no arrest. Twelve people saw enough evidence to justify an arrest, based simply on probable cause. If the one person who mucked things up would have done his job, we all would have seen evidence up the ying yang come out at a trial which probably would have convinced another group of twelve that JB's parents were rightfully arrested for her wrongful death.
AH balked by stating "not enough evidence". Travesty. That child had her skull cracked open, was violated in a heinous manner, and suffered through having the breath of life choked out of her. You can doubt till you're blue in the face that there is enough total evidence to arrest John Ramsey for Felony Murder -- and you will be in the company of some others who agree with you. But I believe JB would have received justice by now if this case would have happened anywhere else but in Boulder, at the time AH was DA.
