Do you know what crimes are considered "serious crimes"? What kind of sanctions are imposed on these crimes? Are the same sanctions imposed on crimes considered to be "serious" all over the world?

It is considered that a crime is serious when the sanction imposed is greater than 5 years of deprivation of liberty.

In all countries, the same crimes are not considered as "serious", but as a general rule, they do all consider as serious crimes: terrorism, intentional homicide, kidnapping, rape, drug trafficking, human trafficking, and crimes that threaten the national security of the country in which the offense is committed.
