Honestly I have to say I may agree with the ruling.
The story does not give enough details to be sure. Was there a fire or just over reaction after someone crashed?
If the vehicle was on fire things would be different. If the person was laying in traffic draggin them to safety is fine. If a person is just sitting in a wrecked vehicle and help is about to arrive.
To rush over to a vehicle that just hit a pole and yank someone out violently with no regard for potentialy spinal injuries is dangerous.
It will often result in worse injuries than if someone waited a few more minutes for medical personel to arrive.
If you want to rescue someone not in immediate life threatening danger after they experience a major trauma, you need to keep thier head from moving.
Many people who have suffered serious neck and spinal injuries such as fractures in accidents including vehicular accidents have since made a full recovery. In fact most do.
People running around throwing people around with broken necks is really dangerous.
It can mean the difference between whether the person can ever move again, or may have just been better off dying altogether.
The risk of permanent damage is really high, much higher than thier likeliness of dying by waiting a few more minutes or operating slower and more carefuly.
Imagine becoming permanently paralyzed after a car accident you would have been just fine from because someone came along and threw you around.
The court case merely says:
he or she has a duty to exercise due care.
It does not mean people are automaticly liable, just that they are not automaticly never liable.
