First post on this case, but I've been following it since the beginning ...
I'm compelled to discount the involvement of any major DDs. If I thought there were violent DDs ready to pounce if anyone opens their mouth, you couldn't pay me a million dollars to return to Bloomington. I think it says something that all PsOI returned - either stranger abduction (agree with RS that it's unlikely, but still possible), or only a very small number of people are involved and agreed among themselves to return and continue to feign ingorance.
This same apparent lack of fear also make me think that if JW and/or the Smallwood altercation guys are involved, then JR, CR and MB (or just CR and MB) may not know anything and therefore are not afraid. Also, as the mom of a recent college graduate, I can't see allowing my kid to return if I thought there was any sort of retaliation or " keep quiet" danger.
Does this make sense to anyone else?
