High Quality Content by WIKIPEDIA articles! Crimes against humanity, as defined by the Rome Statute of the International Criminal Court Explanatory Memorandum, "are particularly odious offenses in that they constitute a serious attack on human dignity or grave humiliation or a degradation of one or more human beings. They are not isolated or sporadic events, but are part either of a government policy (although the perpetrators need not identify themselves with this policy) or of a wide practice of atrocities tolerated or condoned by a government or a de facto authority. Murder; extermination; torture; rape; political, racial, or religious persecution and other inhumane acts reach the threshold of crimes against humanity only if they are part of a widespread or systematic practice. Isolated inhumane acts of this nature may constitute grave infringements of human rights, or depending on the circumstances, war crimes, but may fall short of falling into the category of crimes under discussion."
