What if I can't prove someone's negligence caused my injury?

Some persons or companies may be held "strictly liable" for certain activities that harm others, even if they have not acted negligently or with wrongful intent. Under this theory, a person injured by a defective or unexpectedly dangerous product, for instance, may recover compensation from the maker or seller of the product without showing that the manufacturer or seller was actually negligent. Also, persons or companies engaged in using explosives, storing dangerous substances, or keeping dangerous animals can be strictly liable for harm caused to others as a result of such activities.
