"But, but, but, I do not think there is enough evidence to arrest or convict him. There are other scenarios still possible, and not highly improbable."
Oh I agree entirely. But I don't believe there are any that involve CR or MB without JR's knowledge, nor do I believe that JR would continue to cover the others for something for which he has no responsibility.
As to the notion that JR is covering for JW, that is 100% inconsistent with my understanding of the attitude of JW's friends towards JR. Even apart from that, I see no reason why JR would do so - sharing a fraternity membership alone is not enough when you are facing a potential manslaughter charge or worse.
Re the question about JR's roommates - it is my understanding that he had 4 (one of the units at 5NT is a 5-bedroom, though I don't know that this is JR's), that none of them are his fraternity brothers, and that all of them had left Bloomington prior to the night in question, ie he presumably had the apartment to himself, unless there was a subletter.
As to the continuing discontent with JW's public profile - perhaps he is not giving the public attention to the investigation you desire because he has a very good idea/theory about what happened to LS, and believes that the only fruitful avenue of investigation involves greater responsiveness from another POI over whom he has no control.
As to his going home, he did so after a week to 10 days in town (he was present as of at least the 9th and probably the 10th) with his probably dead girlfriend's face plastered all over town. People seem to be angry at him for not sating their desire to prove something to them, rather than doing whatever he can, without a public profile, for police and LS's family. While I can't speak directly to the former, it is my impression that the latter have no problem with JW.
Re: the 2:30 witnesses and whether information got back to JW, it is my (possibly mis)understanding that one group of JW's friends were with him (at their unofficial frat place 10 blocks from Smallwood) until that time, when he went to bed, and that another group (which I have seen characterized as friends of LS as well as JW, and also identified as including unidentified POIs) were surprised to encounter LS and CR at the same time (perhaps conveniently simultaneously, I might agree) at Smallwood. While that confrontation, certainly, and perhaps also the reported second "confrontation" at 5 North were between CR and friends of JW, my perception is that perhaps the former and certainly the latter (assuming it occurred after LS was discovered missing) were concerned for LS's safety, given not just CR's intentions but the recreational activity of the evening, as much if not moreso than they were for JW/LS's relationship, which some such as HT have emphasized (perhaps unconvincingly, I might agree) was solid and unlikely to be strayed from. Whatever the concern at that time, my perception now is that JW's friends are far more concerned about what JR may have done than what CR did. I agree that that would be logical at this point, from a strategic perspective, in the event that they were seeking to manage expectations on behalf of JW, but I find that eventuality rather improbable - the interests of the frat are strong enough to rally around one guy's crime while blaming it on another member? Come on.
Again, my purpose is not to take attention off JW. It is to put it on whoever else may be responsible, whether that is JR (which I believe quite possible) and/or an unknown person (also possible), or another POI (which I believe less probable).
Re what someone said about "daddy's lawyer," by the way, I don't believe that any of the POIs have hired someone who represented a relative, but my perception is that JR's very wealthy family (check their address), which includes an attorney, is responsible for arranging his big-time representation, which has already been discussed here. I believe JW has hired a 35-year old local (who interestingly has a substantial background in area drug prosecution/investigation).
