Writing Feedback / IELTS task 2: Both views: fixed punishment for crime or case by case consideration [6]

Overall I think is a good essay. Grammar very good
On the second paragraph I would recommend you to add an example. Eg. despite the severity of the offense, every act of robbery should be sentenced with 3 days of imprisonment. Or better give an example regarding your explanation of grey areas....

the conclusion is clear but I suggest to paraphrase the introduction.
