So we are right about why LE hasn't arrested or charged either. Still playing them. Don't have enough without AB, and yet can't get what they need til EB gets mad enough or smart enough to give him up.
So they will wait fo rEB to sweeten the pot to offer her any deal. Then arrest AB, then play them both against one another depending on whose version can be proved, leave teh door open enough to get the perps for the highest chages provable.
