Getting a grand jury to hand down an indictment for this highly sensationalized case is hardly evidence of competency by either the BPD or the Prosecutor's Office, despite the fact that they were highly uncoordinated and even viciously antagonistic toward each other during much of the investigation.
LE could have discovered the body. They did not. Instead, the body was discovered by JR while he and FW were directed by Det. Arndt to search the house!
LE could have secured the crime scene. They did not. Instead, they allowed it to be literally trampled under foot.
LE could have recognized the most likely scenario of this murder as being a burglary gone bad, given that the Ramseys had definite travel plans and were, in fact, scheduled to leave for Michigan that very morning. They did not. Instead, they jumped to the conclusion that one or both of the parents had brutally murdered JonBenet and attempted to stage a kidnapping, and then they held fast to this presumption even after no one in the Ramsey household could be positively identified has having authored the ransom note, using their own rhetoric about Patsy Ramsey "not being completed ruled out" as a means of reinforcing their own self-deception as to the identity of the likely culprits.
In the meantime, with each passing day, the actual murderers were getting further and further away from the possibility of ever being charged. Sixteen years later, this case remains unsolved when the perpetrators could have been discovered had a modicum of common sense and professional expertise been applied from the very start of the investigation.
