Well, the way I look at it; there's one leader and two followers. The leader thought it out "to a T", where the other two weren't too sure. It was sloppy and they messed up on a bunch of things but it went according to plan for the most part so they're keeping their mouths shut.
Of course, they also didn't think about the consequences of WHEN they got caught. Because there is no "IF" here..it's WHEN. Most likely, these people have families and little kids of their own. The other two/or just the weakest of the two, were probably threatened that the same would happen to them if they opened their mouths. Which by all means if the "leader" thinks they're that powerful, then they should be scared. But they should have been scared enough to realize, if they let this person/s DO this and get away with it..they're going to do it AGAIN. Once an ordinary person takes a life in their own hands, they'll WANT to do it again. For the thrill of it. And next time it could be unprovoked, without motive. JMHO
We're looking for someone who has "control issues" who likes to be "in charge" of every situation. Someone that "if you tangle with then it could have serious consequences." I think this person is smart enough to think out every detail, and try to head off LE in every serious line of questioning. But when provoked could provide the information they need.
I wish LE the best in everything they do. Hopefully they've come to the same conclusions as we have as to WHO and WHY. And they'll nail whomever has anything to do with it. Justice4Jessica. MOO, as always.
