tiptopper:
it is not even from the UK, the traffic is on the wrong side of the street.
Perhaps all the drivers were distracted.
Annamarie: in terms of natural justice, I understand your argument. However, imagine the reaction of friends and family of someone killed by a careless driver (one of my relatives was so killed, so I know what I'm talking about) if the driver was punished no worse than if (s)he had gone through a red light, broken the speed limit or whatever with no damage done. Consider how often businesses break safety regulations, with only a small chance someone will be seriously injured. Mostly they'll get away with it because the breaches won't be identified outside the company; so if they're caught, that's already unfair in your terms for them to be punished at all. If the 5% chance happens and one of the workers gets killed, should they not be punished at all, or get only a small fine? If you do an irresponsible act knowing there is a risk someone will die or be seriously injured as a result, you accept the risk and should accept the punishment if you - and your victim - get unlucky. Consider also that civil law will punish a negligent person or agency severely through damages if their negligence leads to death or permanent, serious injury, but not punish them if luckily their negligence leads to no harm. That's because the victim or the victim's nearest and dearest are considered to deserve compensation - but it's still unfair, by your argument, for the perpetrator.
