Crime reduction in the US from 1990s-2000s based off of a book listed in Order instructions”

i selected other for my subject because it is a Criminal Justice class and i did not see that option. all i saw was law, but this paper is not regarding law. A dramatic crime reduction occurred throughout the US from 1990s-2000. an even more significant drop occurred in NYC. what are the reasons? possible to continue declining forever? is it known why NYC had greater reduction? any Master Works that could supply insight? what is your critical thinking opinion?BASED OFF OF BOOK The city That Became Safe: NYs Lessons for Urban Crime and its Control. (this is the only source needed, others can be added as well)
