But, I do think they all shot someone. I think that would have been part of the deal.
And, I think they would know shooting 1 person or 2 is the same charge and punishment as shooting 5 or 7 or whatever. The worked in concert and that's all it takes and their attorneys have surely explained all this to them by now.
As I say, I don't know them so I can only have an opinion... if they were crazy enough to all agree to kill 8 people, then a sick cohesiveness must exist, imo... so, I think they're crazy enough to stick together.
The selfish motivation, however is strongest, imo... the idea that saying nothing is best because I think they all 4 believe they'll still, somehow, get away with these murders. If they turn, then they'd have to tell their story, or their part in it, and then gone is the opportunity to somehow weasel out of it. It would be blowing their own covers, iow. Nope, I think they're going to play,
"You got the wrong people. We didn't kill anybody," all the way until the end.
But, who knows.
Yes, the arrests were laser focused, too. LE's adrenaline must have been soaring... the day they worked so hard towards had finally come.
