That's quite a bit different though, on several levels. Ignoring that that wouldn't be a murder charge anyway, death by dangerous driving I think:what if your driving home from the pub in your mates car and he's drunk, should you be charged with the murder of the guy crossing the road that he killed? because you were in the car with him and didn't stop him
- you weren't the one that put the pedestrian in the way.
- you weren't also drunk driving
- you wouldn't necessarily have known the consequences of your mate driving drunk.
