Well, I do feel for the girl in a way, but for a while, at least, she was probably best behind bars! Hopefully she's gotten her head straightened out by now, though. I feel sorry for everyone who was involved with that madman, honestly. Those kids probably would have been fine had it not been for all the drugs and Manson's brainwashing influences.
As the old Mexican saying goes: "No tiene la culpa el ratón, sino el que le pone el queso" (It's not the fault of the mouse, but of the one that offers the cheese).
