You're right. We don't agree. This is one of the more preposterous theories I have heard. It makes me sad, actually, to think of the absolutely inane hoops that some people will jump through JUST to avoid even considering that this family have known about, or have had something to do with, the death of JB.
It really isn't that complicated to be RDI. It is MUCH harder to be IDI for reasons exactly like this "Korean conspiracy". To blame the killing on Koreans because a PAINTBRUSH had the word "Korea" printed on it defies all logic. I challenge anyone here to go to an art supply store and find a brush that says "Korea" I bet you all will. And if you use that brush marked "Korea" to paint a portrait, pick your nose, or stab someone in the eye, that doesn't mean the Koreans were behind it.
As RDI, I don't look at this crime as premeditated. I look at it from various angles, but the one that is simplest to me and makes the most sense as far as what was done to cover up this death and make it look like a kidnapping/murder are two things- someone was abusing JB and that needed to be kept secret from public knowledge. AND something caused JB to scream that night, and her scream prompted that horrible head bash, meant to shut her up FAST. After that bash, there could be no more screams. Actually, after that bash, there could be no more JB. That's the easy part. The hard part is deciding who did what- because figuring out who did what may also help us figure out WHY. And LE had the same problem; even the DA's office was aware of that. That's why the BPD wanted to separate the parents, to see if their stories differed or if one would rat the other out.
I personally believe that AH and his office DID believe the parents knew what happened and/or were involved. But they also were aware of the ramifications of prosecuting a family with such powerful political clout. In retrospect, given what he probably knew and what he was "advised" to do, AH made the only decision someone in his position and that close to retirement could make. Do nothing. Not even a plea bargain. Just prevent the proper investigation from happening, and the case will never take form.
This does not absolve the BPD from THEIR mistakes, however. They set the stage from the beginning and made the DA's actions possible, even inevitable.
