The field of criminal law has grasped of great interest of the people in today’s community. In this end week, I would like to provide a reflection on what I have learnt from the course. The foremost thing I would like to mention that this gave a platform for learning about substantive criminal law that further helped me in appraising the communal, metaphysical and judicial foundation of criminal categorization. If counted from the beginning, I would like to say that the course covers various historical modification of criminal law in the United States. This course have helped me to gather valuable information on subject matter like parties to crime including the principals or may be substances related to criminal offenses, criminal capability, various elements related to criminal offense.
