Traditional criminal law causality theory is no controversy to determine causality of criminal responsibility, thus it is necessary to introduce the epidemiology causality theory-it is a kind of causality theory based on epidemic diseases, and it is the high degree of probability in the determination of causality in criminal laws so as to solve the traditional attribution problem, but the theory also exists applicable restriction conditions in judicial practice.展开更多
