In these insane times, helping someone can lead to problems best avoided. Eg, moving someone lying on the ground that you come on might lead to their death because you didn't put them in the recovery position, or they were struck by a vehicle and when you moved them you damaged their spine and made them a paraplegic.
In Saudi we were told during orientation that if we were in a taxi that hit someone, rather than render assistance to the injured, we should pay the driver and run away, because we would be held liable for hiring the taxi that hit the pedestrian, and if we saw someone injured on the ground to keep walking or we would be liable if we tried to help them and they died.
