I want to know the answer to the following question:
Has the level of crime in Palermo risen or declined?
All the background I'm provided with is that "Even though the city still suffers from widespread corruption, inefficient bureaucracy and organized crime, the level of crime in Palermo's has gone down dramatically, unemployment has been decreasing and many new, profitable opportunities for growth (especially regarding tourism) have been introduced, making the city safer and better to live in.". Is that enough to answer the question?
