Wait, Sabu's kids were foster kids. He was fostering them. Certainly if he went to jail, they'd go back to the system.

I mean, if you're a sole caretaker and you've been arrested for a crime, and the evidence looks like you'll go to prison, you're going to have to decide what to do with the care of your kids on your mind. I suppose that would pressure you to become an informant instead of taking a longer prison sentence, but there's pressure to do that anyway, like not wanting to be in prison for a long time.
