Well, exactly. And BM seems, and has seemed, to be unable to do this one basic thing to help find his wife! Now, BM comes off as an inarticulate and feckless person, for sure, but for God's sake, make a list to read, stand up in front of the press, and do what you have to do to save your wife.
But he has done none of this. I think BM is a very shallow person, not very intelligent, and has been propped up his whole life. When the poop hits the fan, BM looks to others to mop up the mess. He can't manage his way through some fairly simple actions -- he can't even see that he should be DOING certain actions if he truly cared about SM! He doesn't know that he at least should be faking it for the POLICE. This is why he's been so vague -- he can't do what needs to be done because someone else has always done the social/legal/procedural/etiquette stuff for him. I wonder if that's all SM was to him -- the person who smoothed his way, did the boring household stuff, found the friends, raised the kids, delivered sex, etc.
