Yes, i kind of want to pat LW on the hand and say, this is going to be an awful time for your daughter and her girlfriend - really awful! But you as the disapproving parent now get to be relieved that there is a definite end date on your daughter hanging out with said gf! Which most parents don't get!

This is a wonderful chance for you to support daughter & gf through a really, really tough time, and whenever you can't deal, you get to go out of daughter's earshot and cheerfully remind yourself any serious danger from gf has a time limit. Once gf is physically separated, their relationship will change (still maybe not the way you want it to! But you can build trust now to help her then too.)

(LW is probably not the right person to talk to about the systemic injustices that turn 'dumb teens fail at burglary' into 'murder charges'. But maybe this is a chance for her to listen to her daughter a little? Maybe?)
