For this reason, first I will show the increase and decrease of crime using the Crime Statistics provided by the Walnut Creek Police Department from the years 2014 to 2015, and the years 2015 and 2016. Later, I will use the information in the Community Crime Map of the past 6 months of the year 2016 to established the least and most committed crime in the City of Walnut Creek.
