Strategics and Plans

I am going to research 5 different case studies and view what type of crimes are committed, who they are committed by, when, and where.  Every single one of these aspects that I am going to look into, are all aspects of what an impact society has had on violent crimes.  I am going to use case studies dating back to 2010 - current date and comparing it with statistics from the early  2000's.  Also I would like to take a look at the states the crimes were committed in and what they're social status is like, economy, etc... I hope to find a downgrade or maybe a solution to why these crimes are being committed where, when and why.
