What is Natural crime and What is Legal crime

I need to compare and contrast the concepts or natural crimes and legal crimes. Then list the major crimes used by the FBI in its crime index. Decide which crimes are mala in se or mala prohitita

Am doing a college paper on Natural Crime and Legal Crime and am searching for simple definitions or other research on these two types of crime and what falls under each. Thanks:)

I also would like to know the major crimes used by the FBI in its crime index and which ones are wrong only because it is prohibited by law.:confused: :confused: :confused:

What is the contrast between these two? What may be considered wrong in its self or wrong because its prohibited by law
