"Dangerous Offences and Unlawful Association"

What are crimes of endangerment and are they constitutional? What about unlawful association? Is their application correct? Is the criminal offence well drafted? Does it respect constitutional guarantees, or should it be declared unconstitutional?The intention of the following work is to be able to carry out a correct methodological investigation into the constitutional discussion (doctrinal and jurisprudential) of dangerous crimes in general and the crime of unlawful association in particular.
