The most immediate important thing right now is this search for Hannah. It's going to be over soon, and without her, it may be an uphill battle to keep JM locked up. The other important thing about this case is for a danger perp to be locked up so he does harm others. JM is clearly a loose cannon, a danger to himself and others. Whether he killed Hannah or not, he's not giving up one bit of info to find her. he's hurting a lot of people in the time and resources this search is taking.
However, the reality is that unless there is a ton of very good evidence that LE has and isn't sharing with us, there isn't that great of a case against him. So what that Hannah got into his car? So what he isn't talking? Those things don't count much if anything in terms of the court verdict, and it's something all of us should have clear. These searches are highly emotional for all involved, even those of us sitting a distance away, and it's easy to get "Tunnel Vision" as Longo has warned and we think we have the case is clear, when maybe it isn't
So often entries are not so much of a defense of the guy, but clear rendition of the facts.
It's very difficult on an emotional level for me to understand, and I truly don't emotionally, as to how JM could just sit there and let people search for Hannah when he probably knows well where she is exactly. But a lot is at stake for him, and if he hid her, the very purpose was so that she would NOT be found, so why should he say a word? The reality is that he could walk on this case, as much as most of us would hate to see this, if the search is not successful. So of course he is not going to help. IMO, the best way to have gotten any info out of this guy would have been to appeal to his ego, and have sweet talked him in the beginning. If LE did not do this with someone very good, they lost their chance. Someone getting his car snatched in the middle of the night like that, is going to be very sore and suspicious of LE and not be cooperative, though by this time, would understand the immensity of all of this and help out with all info, if indeed innocent.
