Who is responsible for falling objects from high altitude?

Throwing and falling objects of buildings often cause damage to others, and the damage consequences are often very serious. There is no doubt that the specific infringer is within the scope of building users. However, in many cases of throwing and falling objects from high altitude, it is objectively impossible to find out who committed the infringement, that is, the causal relationship proves to be in trouble. If the victim is allowed to bear the consequences of the damage in this case, it is not only unfair to the victim, but also conniving at the infringement. It is also unacceptable to compensate building users who may cause damage. After all, users of buildings other than specific infringers have not done harm objectively. Therefore, the law stipulates that the building users who may harm the victims should be compensated, that is, everyone upstairs should compensate the victims equally. The people upstairs are not limited to the owners, but may be lessees or temporary users when the infringement occurs. Compensation for the damage of the victim not only protects the legitimate rights and interests of the victim, but also makes the building users more psychologically acceptable, which is conducive to easing contradictions and solving disputes. At the same time, the law also stipulates that building users can prove that there is no causal relationship between the damage consequences and themselves, eliminate the causal relationship to prove their innocence and prove that they are not infringers, thus being exempted from liability.
