mostly occurred in Chicago.
• In weekdays, the crime rate is found considerably high in Street and
apartments. No effect of weekdays or working days was found in crime
rate as the rate is high in Tuesday and Wednesday and low in Friday and
Saturday.

Recommendations to the Police
Chief:
• Theft being one of the most commonly occurring the department needs
to be stricter in these aspects.
• The crime on streets and residents being increasing over the years, the
department needs to increase its vigilance in these areas.
• The number of relevant arrests should be increased and stricter laws
should be imposed.
• The patrolling and vigilance need to be high on weekdays as the crime
rates can be seen to be higher in the apartments in these days.

Research Reflection:
