I was honestly wondering, because it seems that just about anyone would break the law in order to save a loved one, and most wouldn't hesitate. The responses here indicate that.
Laws are artificial constructs, rules of behavior, generally meaningless in the big picture. True, things like murder are illegal, but that's just a formalization of something that everyone would agree is morally wrong. If you have to decide whether to kill somebody in order to save your wife/girlfriend/child/mom, the fact that it's illegal isn't going to be the deciding factor.
Given that, things like breaking into a pharmacy to get medicine for a sick child because you know it's there and you know it'll save him/her, that's a no-brainer. Yeah, stealing is wrong too, but hey, I'll pay them back later.
Things like speeding to get your mom to the hospital, even less of an issue. I don't even care if the cops chase me with sirens blaring. They can follow me and I'll explain it all after we get to the E.R. Some sign or dude with a badge telling me I "can't" go faster than a certain speed means absolutely zip to me. Right now, I'm going as fast as I can.
