Had your car smashed in the work car park are you responsible?

Had your car smashed in the work car park are you responsible?
Where I live:
Rule 1: car or person causing the damage is responsible.
Rule 2: In the case of a hit and run where the at fault driver can not be caught your insurance needs to cover the damage
Rule 3: The owner of the car park is not at fault ever UNLESS you can show how "He" was negligent and contributed to the damage.
