Answer:
Some of the most accurate theories regarding the decline in the number of violent crimes that has taken place in recent years are the following:
-A greater presence of the government in prevention tasks, be it through the police, intelligence services or the National Security Agency itself, coordinating preventive measures to avoid this type of situation.
-An economic stability on the part of citizens, which means that they do not have to resort to crime as a means of survival, given the abundance of jobs and, therefore, the lack of economic needs on the part of individuals.
